Chili 1.x did not enforce the presence of an author for wiki pages, but Chili 2.x does. This migrations fails, if there are WikiPages or Versions without author. By updating the migration, we may ensure, that the erroneous pages are correctly updated.

This will cause the class to run acts_as_journal which will create the
Journal sub-classes and prevent uninitialized constants since the sub-classes
are created on the fly.

If the Journal or the Journaled object don't save successfully,
put out the reasons why instead of aborting the migrations. Journaled
objects might failure from the :touch update, which are safe to ignore.

Was due to Journals touching the parent record but the Journal
not having it's STI class correct during the type update.

So the initial journal would have the changes from an Object#new
to the created version of the Object. Also includes a change to the
database migration in order to create these initial journals for
all journaled Objects.
