Do not restart process of a finishing activity

The destruction operation should have higher priority.
That also avoids disturbing DESTROYING state when the
client reports destroyed.

Currently some callers of restartProcessIfVisible such as
ActivityTaskManagerInternal and TaskOrganizerController
also ignore finishing activity. So this just adds a double
check for the path from config change.
