calendarMessageList: Remove sections map and use clutter children

Browse Source 
Now that the calendar message list and the message sections are actors, there's
no need to keep track of the sections in a different Map as we can just use the
native clutter functions to manage the children and access to their properties.

Also cleanup the signal connection/disconnection.
