layout: fix "elm,state,text,hidden" signal never be emitted

In _elm_layout_text_set function, text_signal_emit is called.
But in that case, check text whether it is null or not null before call signal_emit.
So "text" is not null always, and text_signal_emit's parameter "visible" is also always EINA_TRUE.
