Log message:
    Fix tuple-chain-moving tests to handle marked-for-update tuples correctly
    (they are not part of a chain).  When failing to find a parent tuple in
    an update chain, emit a warning and abandon repair_frag, but do not give
    an error as before.  This should eliminate the infamous 'No one parent tuple
    was found' failure, which we now realize is not a can't-happen condition
    but a perfectly valid database state.  Per recent pghackers discussion.
