#1802 Traffic channels stuck in TEARDOWN. Resolves: (#1829)

Browse Source 
1. Tuner channel processing runnables were being interruptibly shutdown, preventing the channel from clearing any owned locks (ie DMRTrafficChannelManager) causing thread deadlock and eventually causing out of memory situation or tying up all threads in the thread pool to the point that the application stopped processing any data.

2. DMR Traffic Channel Manager was erroneously processing non-owned traffic channel events.
