clutter/actor: Always query layout manager when getting size

Browse Source 
There are cases where a layout manager used by an actor also wants to
return a custom size when the actor has no children, for example in case
the layout manager requests a fixed size. This is currently impossible
because we only query the layout manager when calculating the preferred
size if the actor has children.

So fix that and also use the layout managers size negotiation functions
in case the actor has no children.
