rewritePath function in BeforeFilterFunctions doesn't support url encoded

[RomainPro76]

Describe the bug
I'm using the function rewritePath in org.springframework.cloud.gatexay.server.mvc.BeforeFilterFunctions in a RouterFunction policy. It works well excepts when the url contains an encoded character.
With an encoded character (ex /testé), the output url will transform as /test%25C3%25A9 instead of /test%C3%A9.

In fact, in the rewritePath method, it doesn't take into account the encoded url :

URI rewrittenUri = UriComponentsBuilder.fromUri(request.uri()).replacePath(newPath).build().toUri();

It works well with :

URI rewrittenUri = UriComponentsBuilder.fromUri(request.uri()).replacePath(newPath).build(true).toUri();

Is it intended that the rewritePath method be written like this ? or is it a bug ?

Test case

call the gateway app with an accentuated character in the url (ex: GET /testé). your http client librairie will encoded the url as GET /test%C3%A9. and the output will be /test%25C3%25A9.
