Fix crash when making emergency calls

When making an emergency call the fallback connection
manager would crash. The problem was that the connection
manager would get a setVideoProvider() call even though
it wasn't routing calls.

The root cause of this crash is b/19185063. As a short term
work around I'm adding a null check to avoid the crash.
