Previously, the 'All Pages' view was not sorted alphabetically. We need
to sort on the lowercase version of the page names so that lowercase
names do not end up at the bottom of the list and are instead mixed in
alphabetically, as they should be.
Patches test/test_latest_changes_view.rb to include changes needed to
test alphabetical sorting.
The previous test implementation was dependent on the git configuration:
renames = copies
It could then pass on a computer with that config but not passe on
a different developpeur computer who could have a different git configuration.
That new implementation is testing the same behaviour but at a lower
level and is not dependent on the git configuration anymore.
