Automated tests failing

There are several failed assertions in the tests for Scheduler. The failures are caused by incorrectly enabling Publish and Unpublish on the Page content type in the setup method of the tests. The code currently uses variable_set('scheduler_page', 1); to enable the Publish and Unpublish fields on the Page content type. At some point (didn't check when) the variable names changed so the assertions fails because Scheduler isn't actually enabled for the Page content type.
