repoview: fix typo in repoview.changelog
Incidentally, this avoids the changelog cache being invalidated each time
it's accessed on a repoview.
On a filtering experiment on a repository the size of mozilla-central,
this makes a significant difference:
Before, running hg log -l 10 --time with about 8k changesets filtered out:
time: real 1.490 secs (user 1.450+0.000 sys 0.040+0.000)
After:
time: real 0.540 secs (user 0.530+0.000 sys 0.010+0.000)
