    gcal-timeline: completed_calendars should be unsigned
    
    In on_calendar_monitor_completed_cb() we have this assert:
    
    g_assert (self->completed_calendars <= g_hash_table_size (self->calendars));
    
    That is comparing a signed integer to unsigned. This is dangerous. We
    could add casts to say that we really want to do it, but
    completed_calendars should never be negative, so might as well use
    unsigned.
