Error: Callback was already called

Hello, I found a stack trace leading to a callback error of being called multiple times.

I narrowed it down where it happens in my code, and where it is happening should not be a problem on my side.

Checking the vimeo.js file I can see that on "Vimeo.prototype.request" it would call "_handleRequest" using the same callback as when it is checking for req.on('error").

If both were to run at the same request, that is a request that was sent and then received an error, this would cause the callback to be called twice causing the stacktrace.

Update:
I was able to reproduce the error by closing my internet connection right after the first request is sent.
Apparently, the line 138 gets called twice. That is caused by a retry on the "request" module, making the callback function with the error message to run twice.
Adding a req.abort after the first error seems to avoid the problem, preventing the default retry behavior.
