      Dropping an admin.system.* index while in FCV 4.0 can hit this invariant on startup.

      This invariant is not true in FCV 4.0 because hybrid indexes are only enabled in FCV 4.2, so all indexes built during startup recovery will be built in the foreground. We should remove the invariant altogether.
