NPE on opening youtube channel URLs

[luk1337]

Example URL that will crash the app: https://www.youtube.com/channel/1337. At first I wanted to fix it myself but it looks like the version "1.0.1.1" is not on git repo, nor is YTPlayer.kt present on the master branch thus I'm reporting it here instead.
