Catch SIP exceptions which can crash Phone process on answer.

There are two exceptions which can be raised when answering a call which
can cause the Phone process to crash on answer.
1. IllegalStateException due to answering a call with an incompatible
codec.
2. IllegalArgumentException due to answering a call with a malformed
SDP.
In both of these cases we catch the exception and reject the call to stop
it from ringing (otherwise it will keep ringing and the user will not be
able to stop it).

The existing CallStateException does not require onReject to be called as
it is thrown when the call has already been disconnected before it can be
answered.
