Optimize GetExtensionOrAppIDByURL

When the function reaches this point in the code, then
url.SchemeIs(kExtensionScheme) was false.
So the condition will remain false in GetExtensionOrAppByURL,
which makes this method equivalent to GetHostedAppByURL.
Save some cycles by calling GetHostedAppByURL directly.
