src: remove HandleWrap instances from list once closed

This allows keeping `BaseObjectPtr`s to `HandleWrap` instances.
Previously, the pointer kept the `HandleWrap` object alive, leaving
the Environment cleanup code that waits for the handle list to drain
in a busy loop, because only the `HandleWrap` destructor removed
the item from the list.
