* Make the "latest succeeded" query (used by the "latest" channel)

faster, from about 4.5s to 1.0s for the global "latest" channel.
  Note that the query is only fast if the "IndexBuildsOnJob" and
  "IndexBuildsOnJobAndIsCurrent" indices are dropped - if they exist,
  PostgreSQL will use those instead of the more efficient
  "IndexBuildsOnJobFinishedId" index.  Looks like a bug in the planner
  to me...
