push_notifications: Handle errors with token reuse.

Browse Source 
If an Android token has been used to connect a given device with
multiple Zulip servers, and then is expired, we would 500 in trying to
remove the Zulip-side registration for it, because the code assumed
there was only one such registration.  If a token is no longer valid,
it's invalid for all servers, so the correct fix is to just remove them all.
