revset: use a baseset in _notpublic()

The '_notpublic()' internal revset was "returning" a set. That was wrong. We now
return a 'baseset' as appropriate. This has no effect on performance in most case,
because we do the exact same operation than what the combination with a
'fullreposet' was doing. This as a small effect on some operation when combined
with other set, because we now apply the filtering in all cases. I think the
correctness is worth the impact on some corner cases. The optimizer should take
care of these corner cases anyway.
