clfilter: prevent unwanted warning about filtered parents as unknown...

clfilter: prevent unwanted warning about filtered parents as unknown During changectx __init__ the dirstate's parents MAY be checked. If the repo is filtered, this check will complain "working directory has unknown parents" even if the parents are perfectly known. This may happen when the repo is used for serving and the dirstate has parents that are secret, as those secret changesets will be filtered.
