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)

  $ hg init
  $ echo a > a
  $ hg ci -Am0
  adding a

  $ hg -q clone . foo

  $ touch .hg/store/journal

  $ echo foo > a
  $ hg ci -Am0
  abort: abandoned transaction found!
  (run 'hg recover' to clean up transaction)
  [255]

  $ hg recover
  rolling back interrupted transaction

Check that zero-size journals are correctly aborted:

#if unix-permissions no-root
  $ hg bundle -qa repo.hg
  $ chmod -w foo/.hg/store/00changelog.i

  $ hg -R foo unbundle repo.hg
  adding changesets
  abort: Permission denied: $TESTTMP/foo/.hg/store/.00changelog.i-* (glob)
  [255]

  $ if test -f foo/.hg/store/journal; then echo 'journal exists :-('; fi
#endif
