Issue with video link with query parameter in it

[shenyush]

If the videos in side the m3u8 list look like
https://www.google.com/video0.ts?some=else
The path_helper.py will resolve the file name (function resolve_file_name_by_uri) to video0.ts?some=else, and it wouldn't work (at least on Windows, didn't try it on Linux).

The fix would be adding a split by ? to remove any query parameters.
name = uri.split('/')[-1].split('?')[0]
