manager: Delay UI Call removal and adjust to changes

This was handled explicitly in the Call window.
By changing the logic to delay the emission of "ui-call-removed" we make sure
that the Call UI and the exported DBus object is consistent.

We also need to change the test cases to use run a GMainLoop because we now have
to wait until signal comes in.
