[FIX] Some fixes

[djorkaeffalexandre]

• Configurable Custom Headers to rest/websocket
• Resolve any send (unsub need an id emit)
• Clear timeout/interval at close function instead onClose, apparently sometimes onClose is called with code 1000 by other handler
• reopen immediately when called instead after timeout
• send some message await an open event when send before the websocket readyState equal 1
• resubscribe with the same id, no duplicate streams
  • Open a stream, minimize the app, back after 60 seconds, it'll call subscribeAll and send the same id of the previous streams
• Handle open retry
