Timothy Gu 99b27ce99a url: prioritize toString when stringifying
The ES addition operator calls the ToPrimitive() abstract operation
without hint String, leading a subsequent OrdinaryToPrimitive() to call
valueOf() first on an object rather than the desired toString().

Instead, use template literals which directly call ToString() abstract
operation, per Web IDL spec.
