Log the NSError str and object description on app launch fail

Update CallBoardSystemServiceOpenApplication to unconditionally log
the NSError's localizedDescription to Console on app launch failure
(as it was already doing), and also to log the NSError object's
full description to the console, which may contain additional nested
error messages.  I'm experimenting to find cases where we will get
more detailed information from app launch failures and will start
by logging both to the console.
