Provide context for "unknown provider" errors.

When you get an error like this:

Error: Unknown provider: userProfileProvider <- userProfile

The stack trace is exclusively inside of Angular code, and there is nothing in the error that says which controller's instantiation, or any other object's instantiation, the error is coming from.

There should be enough context to detect where the issue is happening. This is currently very hard to debug.

The issue is that $injector.invoke needs to know about the name of the thing it's instantiating.

It's definitely doable, but would require a bit of refactoring across the codebase

Would you like to tackle it and send a PR?

I've never worked on the Anuglar.js codebase. I was hoping you guys could take care of it.
