Fixes a crash by git-annex repair when .git/annex/journal/ does not exist.
Normally the journal directory is created before withJournalHandle gets
run, but git-annex repair can be run in a situation where it does not
exist.
git add will fail if the file got deleted in the meantime. And since it was
queued, there was a window until the queue flushed where a deletion of the
file would cause a crash.
Instead, reuse Command.Add.addFile, which sha1 hashes the file itself
immediately, and then queues the index update. Ignore exceptions that will
happen if the file got deleted already.

Commit b6642dde8a broke it by enabling
non-concurrent display mode while leaving concurrency set in the config
and having already started concurrency earlier.
(I don't actually know if that commit was a good idea.)

Optimise database to further speed up importing large trees from special
remotes.
See comment for details of why the other index didn't help cid queries.
It would probably be better to manually create an index on only cid, rather
than adding a second uniqueness constraint that is a larger index. But
persitent does not support creating indexes, and an attempt to manually add
it to the migration failed.

This avoids bottlenecking on git check-ignore in a particular situation.
Also, there may have been a correctness issue with it not having updated it.
When the exportdb is already up-to-date, this is not expensive. And the
exportdb is updated elsewhere, so usually it is up-to-date.

Speeds up eg git-annex sync --content by up to 50%. When it does not need
to transfer or drop anything, it now noops a lot more quickly.
I didn't see anything else in sync --content noop loop that could really
be sped up. It has to cat git objects to keys, stat object files, etc.
