P25P1 Traffic Channels Stop Decoding After Control Channel Rotation #1996

Describe the bug
The P25 traffic channel manager is not clearing out channel allocations when the control channel frequency changes after a lose-sync event. This prevents any traffic channel allocations against those frequencies. When users have their channel configuration setup to include some of the traffic channel frequencies in the list of control channel frequenices, this can prevent traffic channel allocations.

To Reproduce
Setup a channel configuration with the control channel and all traffic channel frequencies. Start decoding and then remove the RF input to cause the spectrum to blank. Allow the control channel to rotate through all of the frequencies (and fill the traffic channel allocation map) and then reapply the RF input to the tuner to allow the control channel to be found again. Observe that none of the traffic channels will allocate from this point forward without an app restart.
