Fix ambiguous URI parsing in Youtube Remarkup rule

Browse source 
Summary:
Fixes T12867. Also:

  - Simplify the code a little.
  - Stop mutating this on text/mobile -- there's no inherent value in the "youtu.be" link so I think this just changes the text the user wrote unnecessarily.

Test Plan: {F5013804}
