Media Tools: Sketchfab Mobile app links need to be formatted

[j-conrad]

Using the Sketchfab mobile app on iOS (and probably Android):

Links from the Sketchfab app add a bunch of junk that make the links not work.
On desktop, here is a model link: https://sketchfab.com/models/17cf0dbe4435434eb6e04394fd5bf7ae

On mobile, here is the same model link:

Seems like we should probably just strip out the superfluous text ourselves when the user hits the 'create' button. Otherwise, we'd have to convince Sketchfab to change their formatting.

i'm going to close this for now that we have media content search in place, which should hopefully limit the severity of this.
