[buteo-sync-plugins-social] Use correct incidence comparison function…

…. Contributes to MER#1392

This commit ensures that we use the correct incidence comparison
function when performing local delta detection.  Previously, we used
the one which only detected changes specific to event-types, which
does NOT include those changes which are valid for all incidence types.
