URL should be normalized before trying to match with regex

[ghost]

e.g.
http://tp.srgssr.ch/p/portal?urn=urn%3Asrf%3Aais%3Avideo%3A3fd90c9f-507a-4a79-b6b6-ac55f746b4d4&autoplay=true&legacy=true&width=640&height=360&playerType=

doesn't match, because
urn%3Asrf%3Aais%3Avideo%3A3fd90c9f-507a-4a79-b6b6-ac55f746b4d4
isn't normalized to
urn:srf:ais:video:3fd90c9f-507a-4a79-b6b6-ac55f746b4d4

which would match.

That is a valid URL with correctly encoded parameters.
The regular expression can be improved to correctly match that URL.
But, the parameter should be properly extracted from the URL to properly decode it.
