revert: fix missing removes when parent was changed in dirstate

When dirstate parent is changed with dirstate.setparent before a
revert so it no longer points to where the dirstate refered to, revert
does not remove all files it should:

Revert to a different revision needs also to remove files that are not
found through disptables and not in the context or parent manifest.
