  mf/session: Initialise the stored presentation rate.
  
  The latest argument passed to SetRate() is stored in presentation.rate,
  but if the client never called SetRate(), the stored rate remains zero,
  which results in preroll not being enabled. That could be fixed by
  instead calling GetRate() before enabling preroll, but always setting
  the stored rate reduces the risk of regression.
