Reviewed by Eric Carlson.

We were muting other tabs within UserMediaProcessManager::willCreateMediaStream but only for microphone and camera
as the screen/window code path was exiting early.
Move the call to mute other tabs in WebPageProxy::willStartCapture so that it covers all code paths.

Covered by API test.
