    calendar-server: Update views only after the time range is set
    
    The gnome-shell-calendar-server calls to refresh queries even when it has not
    time range set, which results in:
    a) waste of resources (for example after login),
    b) many runtime warnings in the journalctl log, related to incorrect time range being used.
