In form listings, show formid in parens if there's a formid match with a soft-deleted form

In the following screenshot, neither form in the trash can be undeleted:

One of the forms has a title match with a currently-published one so its formid is shown. That makes it clear where the match is. The other has a different title but a matching formid so no formid is shown.

This is confusing if for some reason a form needs to be undeleted. It came up most recently because a user was trying to figure out what the rules for blocking undelete are. I've seen this case on one other user server.
