Patch

This was generated by a slightly hacked at pyupgrade, to only fix this deprecation warning.

Looks good, but I want to see some successful layout tests before landing, I suspect webkitpy tests aren't completely covering this change.

Python 2.7 and Python 3.3 added it, IIRC. The annoying thing is even once u'' was re-added to Python 3 (in 3.3), ur'' wasn't (because, IIRC, there are syntax differences).
