a few forgotten remote config fields

preferreddir can be used with any special remote, so its parser needs to
be included in the commonFieldParsers.

initremote with uuid= changed to delete that field, so it does not
need to be included in commonFieldParsers. Note that, existing remotes
initialized before this change will have the field in remote.log.
This will not cause problems parsing, because the value will be
Accepted.

Grepping for 'Accepted "' found these, and I'm pretty sure this is all of
them.
