/*! \brief get the where clause for a playlist
We handle playlists inside playlists separately in order to ensure we don't introduce infinite loops
by playlist A including playlist B which also (perhaps via other playlists) then includes playlistA.
\param db the database to use to format up results
\param referencedPlaylists a set of playlists to know when we reach a cycle
\param needWhere whether we need to prepend the where clause with "WHERE "
