Move PhabricatorUser to new phid stuff

Summary: Ref T2715. Had to start loading status information in the query class. Debated trying to clean up some of the attach / load stuff but decided to just add status under the new paradigm for now.

Test Plan: phid.query  also made a status and checked that out. also played in conpherence.
