Check collection less than two items remaining before firing scalar backref remove
Fixed long-standing issue where duplicate collection members would cause a
backref to delete the association between the member and its parent object
when one of the duplicates were removed, as occurs as a side effect of
swapping two objects in one statement.
Fixes: #1103
