Title: Remember if a child has been removed after a failed form post

If the parent object fails validation it doesn't remember the child objects that have previously been marked for deletion.

- Send the object._destroy value param into the hidden_field_tag (link_to_remove_association)

- Hide the nodes that are marked for delete from the previous form submission (js)
