This PR fixes an issue where an incomplete Request object was passed into UrlMatcher, because old Router::match() method was called internally when Router::matchRequest() was used.

New code mimics the old behavior, but instead of creating an entirely new Request object for matching, it duplicates the existing one (using a built-in method) and replaces REQUEST_URI with new path value (the same as used before).

I can confirm that both Admin UI and basic front works with this solution.

Tests were updated to more specifically check what values are used by Matcher.

I've verified that the scenario described in the ticket now works (with a conditionally matcher route). I've also performed basic sanity checks using frontend and admin siteaccesses (using URIElement and Map\Host matchers).

Looks good, QA approved!
