    st/label: Don't guard against NULL text
    
    Commit 9168f6055e marked the parameter as nullable, which is in
    conflict with the precondition check. But given that NULL is
    valid for the underlying ClutterText (and GtkLabel accepts it
    as well), there's no strong argument for disallowing NULL, so
    remove the precondition check.
