I just did nearly the same thing: I deleted a project when attempting to delete a task, and didn't notice until about a hundred actions later. Why doesn't OmniFocus have a trash where these things go? It seems pretty logical, and Things implements it quite nicely without any fuss. You don't even have to sync trashed items –*just that they were trashed like you do now. Any changes while in the trash can be ignored (or even disallowed without being restored).
