LibProtocol: Use URL class in RequestClient::start_request argument

This changes the RequestClient::start_request() method to take a URL
object instead of a URL string as argument. All callers of the method
already had a URL object anyway, and start_request() in turn parses the
URL string back into a URL object. This removes this unnecessary
conversion.
