[empathy] Change the type of EmpathyContact.priv.groups to GeeHashSet.

[Travis Reitter <treitter src gnome org>]

commit a8833fd63b3bc3856cbd885158cba6b8fca1225a
Author: Travis Reitter <travis reitter collabora co uk>

    Change the type of EmpathyContact.priv.groups to GeeHashSet.
    
    This is to adjust to the newer API for folks_group_details_set_groups().
    It's also slightly cleaner than using a hash table to implement a set.
    
    Helps: bgo#648822 - Port Empathy to Folks 0.5.1
