[vreg] object_by_id should not have been deprecated. Fix facets.
it was *designed* to be able to force an object retreival when selection
is potentially not possible.
For instance using select instead of object_by_id in get_facet totally
breaks the implementation since in get_facet we've not context result
set, and we ends up with a NoSelectableObject exception.
