createPlaylist does not guard smart=True and non-empty items

[glensc]

Describe the Bug

Seems server.createPlaylist(self.name, items=items, smart=True, section=section) does not guard smart=True and non empty items.

While other methods like playlist.removeItems() and playlist.addItems() guard that you do not add items with smart playlist.

The outcome is that created smart playlist doesn't actually contain the items, but something more (haven't figured out what yet, seems like the whole library is added to such smart playlist)
