MDL-34807 question bank: navigation loses place.

The symptom is that where we are now is not shown in the settings
navigation. However, the underlying cause is that question/edit.php is
doing some crazy thing of its own to build $PAGE->url, rather than using
the one returned by question_edit_setup.

Not that this patch itentionally removes the returnurl param. It was
added as part of a big change MDL-20276, which I think just got this
detail wrong. That variable is never used.
