PATCH: Fix inverted condition for unique completions

[Mikael Magnusson <mikachu@gmail.com>]

This change makes most-recent-file[1] completion take a few milliseconds
instead of close to a minute in a directory of 30000 files. I'm not sure
exactly what's going on with these flags, but surely if they are not set,
then we should not deduplicate the set of matches. Most likely this was
a thinko-copy-paste-o from the first NOSORT case which does have to be
negated. I'm not sure why regular tab-press was always fast, but it is
still fast after this change for me.

I don't know when these flags are supposed to be set, so I haven't tested
that case.
