Quick & dirty fixes

createYoutubeFilelist requires arg setting4, is never used. added
placeholder nulls when called in [GetCommercialList](https://github.com/DrSpaceMonkey/script.pseudotv.live/blob/89a1b21129dd80645ec666b6d62700758651ba15/resources/lib/ChannelList.py#3421) and [GetTrailerList](https://github.com/DrSpaceMonkey/script.pseudotv.live/blob/89a1b21129dd80645ec666b6d62700758651ba15/resources/lib/ChannelList.py#L3603)

Some channels were throwing a pop on empty exception [here](https://github.com/DrSpaceMonkey/script.pseudotv.live/blob/89a1b21129dd80645ec666b6d62700758651ba15/resources/lib/ChannelList.py#L3276).

I got PseudoTV Live running under latest Gotham nightly with these changes.
