Pass the TelecomManager#placecall calling package through to TC logs.

Ensure the calling package is logged in the telecom dumpsys when an
outgoing call is placed.  Makes it easier to diagnose when a mysterious
call was placed but we don't know the origin.

Also add notification channel for test app so we can actually see the
notifications it posts.

Test: Ran unit tests for regression checking.
Test: Manual - inspection of logs.
