Fix black screen flashing during sip calls

Add the same delayed finish logic that is in OutgoingCallBroadcaster
to SipCallOptionHandler. This is needed because SipCallOptionHandler now
lives in a separate process from InCallActivity, so calling finish
immediately would cause a black screen before the InCallUI comes up.
