clutter/text: Don't query preferred size without allocation

Browse Source 
The size request functions query the resource scale, which hits
an assert if headless. The returned sizes are already only used
when clutter_actor_has_allocation() is true, so this doesn't
change the condition for calling either redraw or relayout.
