Update "wrong project - moved" message related to Dungeons / Legends removal

[MikeUnverferth]

Now that Dungeons and Legends are closed for new bug reports, these should be removed from the "Wrong Project - Moved" message.

Also, the Invalid / Wrong Project message should be removed entirely. Instead of asking the reporter to create another issue, just use the Wrong Project - Moved message and "move" the issue accordingly. If not authorized for that, submit request in appropriate channel for someone who is authorized to actually move it.
