Debug tools for Antelope lib

[Viterbo]

Fixes #689 and #745

Description

This PR includes changes for two different issues. First, it incorporates a whole new functionality on the Antlib to provide tools for debugging. Then, there are some code refactors to remove unnecessary dependencies.

Antlib debug tools (#689)

This is the list of features implemented.

• The debug mode can be turned on (and off) using a URL parameter like this trace=true but now is remembered in localStorage. It remains on if you lose the parameter while you navigate.
• You can print the current state of the stores to see the actual data
• When debug mode is on, you can access Antlib from the console and execute any valid function

Dependencies removed (#745)

All proposed changes here were made. I will explain how I replaced those dependencies.

• Chan: needs to query the current stake/unstake ratio and for that, it used Account and Contract stores. That was removed with a direct ethers.Contract creation using the getAntelope().wallets.getWeb3Provider(); global function to solve the provider.
• Contract: was using the Account store to get the authenticator and provide a signer for the contracts. The code was copied from OBE's code but the reality is that we don't need them anymore because we solve all signing with the EVMAuthenticators and they use their own signer. So, although there's no need for this functionality anymore, I refactored all functions to receive a final optional parameter bringing an ethers.Signer if for some reason the developer wants to sign this way.
• EVM: was using the Account store to initialize an InjectedAuthenticator. Now that initialization occurs inside the Authenticator itself. So, the EVM store now does not need to depend on Account store anymore
• Account: was calling a clear function one by one on all its dependencies. That code was replaced with a new event called getAntelope().events.onClear that passes the label indicating which context we need to clear (thinking of the future when we have multiple connections, we don't want to clean them all).

Test scenarios

Let's check the new Library debugging features:

Debug mode (on & off)

• go to this link with the trace = true https://deploy-preview-690--wallet-staging.netlify.app/?trace=true
• open console (F12)
  • you should see the trace turned on and some traces
• Login
  • you should see all Antlib login related funcion being executed
  • You lost the trace=true parameter in the url
  • now press F5 with no trace in the URL
    • you should keep seeing all traces
• To turn off the debug mode by accessing: https://deploy-preview-690--wallet-staging.netlify.app/?trace=false
  • open the console
  • you should not see any trace

Print:

• Turn on debug mode again: https://deploy-preview-690--wallet-staging.netlify.app/?trace=true
• Open console
• Enter the following text in the console: ant.print()
  • you should see an explorable tree of data on every store

Filtering traces

• Turn on debug mode again: https://deploy-preview-690--wallet-staging.netlify.app/?trace=true
• Login
• Open and lean the console
  • You will see that the update-related functions are called every now and then, which is annoying for debugging.
• Enter the following text in the console: ant.debug.filterStart()
  • you will notice that the traces continue but don't repeat.
  • after you get everything filtered, enter the following text: ant.debug.filterEnd()
  • now you will get trace only for your actions
