Refresh failed for AppService instances with v0.12.0-preview

[ggogel]

What happened?

I created several instances of type AppService. Then upgraded provider-jet-azure from 0.11.0-preview to 0.12.0-preview. The AppService instances can not be refreshed anymore.

CannotObserveExternalResource
cannot run refresh: refresh failed: parsing Azure ID: parse "SystemAssigned": invalid URI for request: : File name: main.tf.json

How can we reproduce it?

1. Install version 0.12.0-preview
2. Create an instance of AppService
3. Watch events and see that resource cannot be refreshed
