Mike Bayer 1393eac44c Implement remove() for _empty_collection
Fixed regression caused in 1.2.3 due to fix from 🎫`4181` where
the changes to the event system involving :class:`.Engine` and
:class:`.OptionEngine` did not accommodate for event removals, which
would raise an ``AttributeError`` when invoked at the class
level.
