Fix mass updates of the form `mass update A -> B` not being allowed. This was originally because after `rename` was introduced, we wanted to prevent people from using mass updates to move tags. Now, `mass update A -> B` adds B to all posts tagged A instead of moving A to B. So `mass update A -> B` should no longer be disallowed. This also makes it so that it's an error to create a mass update with a syntax error in the search. Before searches couldn't have syntax errors, but now with the new query parser it's possible.
