call: update conference state to OVER on remove

The conference state is never updated when its removed since
no changed signal is emitted with an updated state. This sets
the state to OVER when we receive the "conferenceRemoved" signal.

The renderer must be removed with deleteLater() due to pending
slot/signal connections.
