[Request] Merged empty widget better be not even shown

[jesuslop]

Hi Doc. Currently when I merge from two widgets, say a Movie widget and a TV Show one (from addons), and combine them in an autowidget, if one source is empty, for instance there are no TV Shows, then the combined widget show this adding a special nullish item to the list. ¿Couldn't this not be added? So if there is only movies just show the movies, not adding the dangling extra empty item saying there's no shows.
