fix(GODT-2764): Allow perma-delete for messages which still have labels

Browse Source 
Rather than match the web client behavior (removing labels) when
messages are appended to trash, we simply omit the check to see if the
message in trash is present in other labels.

This will produce the same end result and will resolve the issue of
users not being able to fully delete their messages.
