Implement part of the test call video provider.

- Add option to "add video" to the call service notifier.
- Set TestCallVideoProvider in TestConnectionService when adding a
call.
- Implement some of the stubs in TestCallVideoProvider. For now,
they're pretty dumb in how they handle function calls and return.
