knotserver: redirect handle-path to did-path
this will allow handle based url when cloning from knot over https
usually appview will resolve this before redirecting to the knot
this implementation just redirects to resolved path instead of passing
the entire identity for performance. As we won't want to resolve same
identity twice when proxied by appview.
