scmutil: introduce shortesthexnodeidprefix()

We have scmutil.resolvehexnodeidprefix() for resolving a prefix to a
full nodeid, so it makes sense to have the inverse method next to
it. For now it just delegates to changelog.shortest(), but it will
soon also make sure it's called on the unfiltered repo, to match
resolvehexnodeidprefix().

Note that the change in show.py also makes it so the conversion from
revnum to nodeid is done on the filtered repo, but that should be
inconsequential since the revs are all from the filtered repo anyway.
