direct: Fix ugly warning messages.
replaceFileOr was broken and ran the rollback action always.
Luckily, for replaceFile, the rollback action was safe to run, since it
just nuked a temp file that had already been moved into place.
However, when `git annex direct` used replaeFileOr, its rollback printed a
scary message:
/home/joey/tmp/rrrr/.git/annex/misctmp/tmp32268: rename: does not exist (No such file or directory)
There was actually no bad result though.
