Remove BIND_TO_IN_CALL_EMERGENCY_ERROR_UUID anomaly report.

Some ICS may fail to bind and that is normal. This anomaly report has already been removed for non-emergency calls. This CL removes this anomaly report trigger for emergency calls as well as cleaning up the variables that were created for reporting both emergency and non-emergency calls for this type of anomaly report.

Test: Run unit tests InCallControllerTests
