Usually, Org cannot resolve an external link if it doesn't know about
the external file, i.e., if it doesn't publish it.

HTML export is a special case because resolving custom-id links is
trivial (the back-end doesn't alter them). So I guess we can use that to
make it work in this special case, even though it will fail in other
back-ends.

I pushed the change in master. Let me know if it works for you.
