Summary:
Fixes T12628. After later changes to `PhabricatorFile`, this migration no longer runs if you upgrade through it to a recent `HEAD` while your data has some room images.
Since this isn't critical and has been available for ~6 months, I just nuked it as a first pass. I can find a more careful approach which lets us continue to run this migration instead if you're hesitant to skip this step, although it may be a little involved.
In 95% of cases we avoid this by updating the storage table as it existed at the time the migraiton ran, but Files are much too complicated for that to be realistic.
Test Plan: Ran `bin/storage upgrade -f --apply phabricator:20161005.conpherence.image.2.php`, saw it do nothing.

Summary: This moves room pictures out of the dialog and into it's own PictureController. Also adds a standard image (and removes the "last person to chat" picture (though we could add that back. My plan is though that direct messages use auto use the other person's photo, after we have editengine and room pictures will have a plain, replaceable image.
Test Plan: Set a new room picture, remove a picture. Run migration, see old images properly set with new image.
