Tables: Alters entity queries to use a workspace revision instead of the default one.

    // entity query is instructed to query all revisions. However, if we are
    // looking for workspace-specific revisions, we have to force the parent
    // method to always pick the revision tables if the field being queried is
    // revisionable.
