Implement __delete__

A long-standing oversight in the ORM, the ``__delete__`` method for a many-
to-one relationship was non-functional, e.g. for an operation such as ``del
a.b``. This is now implemented and is equivalent to setting the attribute
to ``None``.

Fixes: #4354
Change-Id: I60131a84c007b0bf6f20c5cc5f21a3b96e954046
