st/label: Don't guard against NULL text

Commit 9168f605 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.
