Fix inadvertent forward dependency in task owner migration

Summary:
See <https://github.com/facebook/phabricator/issues/505>. When the status/event table moved, it broke this migration, which implicitly loads statuses by loading events.

Instead, access just the row we care about.

Test Plan: Used `--apply` to apply the new version of the patch.

Speed up diffusion_browsequery for mercurial repositories

Summary:
Ref T4387. By using `hg locate` to attempt to only list files in the given path
browsing diffusion is a bit faster. In a repo of about 600M it shaves a rough 100ms
off viewing the root of the project.

Test Plan: Looked around in diffusion and saw it showed everything including .files, which was nice
