When viewing deleted pages only, the "redirects" option does not apply, since we don't know if deleted pages were redirects.

On the form, when selecting "Only include deleted pages", the Redirects option should change to "Exclude redirects" and become disabled.

In the controller, when a request is made to /{project}/{username}/{namespace}/{redirects}/deleted (any options with deleted-only set), it should redirect to /{project}/{username}/{namespace}/noredirects/deleted.

Accordingly, the summary in the view should not include the "redirects" column.
