Update Truth to snapshot version

This version deprecates the inconsistently named
MultimapSubject#containsExactly. We're getting ahead of the game by
changing it now.

The snapshot was originally downloaded from [1], but only a week's
worth of snapshots are kept around, so we had to copy it to the Gerrit
Maven bucket.

Unfortunately, sources are not published along with snapshots. At
least for the case of Truth, we want this change more than we care
about losing source navigation in Eclipse.
