UI: Fix crash in YoutubeAuth

Browse Source

YoutubeAuth::chat is a raw pointer that is uninitialized. Most of the
time it doesn't matter, since the object it points to is created at the
application start. However, in case of Wayland (Linux), CEF is not
initialized (because it's not supported) and the chat object will never
get created.

This patch fixes crash on Wayland by initializing `chat` to `nullptr`.
