Prevent item deletion on enter key
Prevent item deletion on enter key

If the user is editing an existing item and presses enter, AngularJS
will do an onClick() on the first submit button, which is the (usually) hidden
delete confirmation button in this case. We only want to confirm delete
if the user has previously clicked on the X previously, though.
