Cannot set one-to-many collection key if it matches many-to-many default using bycode.

So I've got an interesting situation switching from inverse false -> true on an existing database. This means adding in Child.Parent property mapped to the existing "parent_key" column - and surprisingly it fails.

This gist covers the details.

I think the issue is here. We refuse to set the column name if it matches the default many-to-many case (ownerentityname_key), but in the case of a one-to-many relationship the default is actually OwnerEntity(?) and this setting would be a valid override.
