Enable logging of InCallScreen creation/deletion in all builds

In normal operation, the InCallScreen should only ever get created once,
and should *never* get destroyed, since we never allow it to finish().

So increase the logging verbosity in onCreate and onDestroy to make it
clear (even in user builds) if we're getting created/destroyed more than
expected.  This is helpful for debugging OOM issues like bug 3100957.
