Catching errors on deletion.

Fixed the fact that error wasn't handled when deleting an item. 
In a project, I had to sync backend with an external Cloud. I used mongoose middleware (pre-remove) to try deleting the same item on the cloud. If something went wrong or deleting is locked (this happens when something is pending), I pass an error to next(). It cancels the deletion, but no message was prompt (flash or console).

Catching errors on deletion.
Removed useless verification on single element

I don't know what was causing findById to return more than one entry when this verification was written, but according to mongoose documentation and my tests in Keystone, this condition (Array.isArray(item)) never returns true in any case (when displaying the view, saving an item, or trying to edit an item that doesn't exist). Of course, I assume that ids are unique, if that's not the case (is that even possible ?), we should handle this error more explicitly.
