[BUGFIX] Determine returnUrl when deleting pages in EditDocumentController

Determine the returnUrl based on the current module and record. If the
delete action if for a record in the table "pages" the backend needs to
perform a partial reload to avoid trying to access the deleted page. In
all other cases the predetermined returnUrl is ok.
