Add exception handling and retry when configuring VVM.

In VoicemailStatus#apply there is a possibility for the call to
ContentResolver#insert(.., ...) to throw an IllegalArgumentException if
the content resolver can't be started.  If this happened there was a
possibility of the entire Phone process dying.

Added exception handling to the apply method, and in the
OmtpVvmCarrierConfigHelper added code to retry configuration if it fails.
