	Added some more test cases as part of the work to fix this bug:

	Radar 3136795 (type URL with ../ in it, get assertion)

	I also notice an unrelated change in ifnsurlextensions-test.chk where
	leading whitespace in a URL is now getting removed correctly. Bonus.

        Radar 3136795 (type URL with ../ in it, get assertion)

        The code to remove relative portions from URLs was eating leading slashes on
        URL paths. This caused absolute paths with relative portions to get mangled,
        resulting in a URL that the engine could not use. Now, leading slashes are no
        longer removed from URL paths, resulting in usuable URLs.
