/dmails: remove unused search[owner_id] param.

/dmails is restricted to viewing dmails for CurrentUser only (due to
Dmail.visible in the index action). Remove owner_id from subnavbar links
in /dmails, and don't support it in /dmails?search[owner_id], since it
doesn't actually do anything.

Also removes related dead methods and fixes tests that didn't test owner_id properly.
