Fix routing for duplicated path

In case where the same combination of "method:path" match the routing it was selected always the first. E.g.: POST:{} and POST:retrieve from KRA `KeyServlet` was not working because always the first was used. Additionally, the routing of servlets and filters are the same and it is not supported anymore filter routing to multiple method using "*" which has never been used.
