Fix paths that check.yaml watches (eclipse-uprotocol#10)

* Fix paths that check.yaml watches

* Fix remote subscribe (eclipse-uprotocol#8)

* Fix UUID and message priority (RPC must at least use CS4)
* Changed other rpc calls also to CS4 and a correct UUID
* Return connection state if a subscriber is already there and handle same client connecting twice
* Fix new remote subscriptions always returning SUBSCRIBE_PENDING, regardless of actual state
