Instance query argument breaks YouTube URL parsing in MediaElement.js

See ticket:36759:8:

Works: [video src="https://youtu.be/mhnuES3Zgr4"]
Broken: [video src="https://www.youtube.com/watch?v=mhnuES3Zgr4"]

That's because wp_video_shortcode() appends an instance argument to the original URL, which results in http://www.youtube.com/watch?v=mhnuES3Zgr4&_=2.
This extra query argument breaks ​this line in MediaElement.js.

I'm going to report this upstream as well.
