Generate new jax-rs Response for every /.well-known/* request

Generate new javax.ws.rs.core.Response every single time when
 request on `/.well-known/*` is processed, so the new output-stream
 will be used for every response.

javax.ws.rs.core.Response.status(Status.OK) creates new
 OutboundMessageContext with CommittingOutputStream, which is
 closed during the process of sending the response to client.
 Closed output-stream caused
 `java.lang.IllegalStateException: The output stream has already
 been closed.` when `/.well-known/*` endpoint was requesting
 multiple times, which made the endpoint working only once.
