The problem with #roster{} is that every new record entry is also stored
in the mnesia roster table. Adding the mix_participant_id there makes
no sense because the normal roster items are no MIX channels. Using
\#roster_item{} for the hook and #roster{} for storing the normal items
seems to be a better idea.
