websockets not closing correctly?

[algar42]

Describe the bug
Everything works fine until we close and re-open browser or open front-end from another device. In this case it looks like the previous ws client is not destroyed and server continue to broadcast to closed connections. As a result with each new connection we get increasing number of data sent to the clients and states update on page reload and/or on another device stop working...

To Reproduce

1. Restart lovelace adapter and open front-end.. at this step everything should work fine even if we just reload the page.
2. Close browser completely -> run browser -> open front-end again.
   At this stage
   a) on page reload we get old data (looks like connection with new client does not init correctly).
   b) we start getting duplicated state_updates from server, i.e. server sends data to the closed connection from point 1.
   Here at the picture only one front-end opened, but states are duplicated:
   

If can't repeat the issue, try to re-load page/ re-open browser couple of times.. at some point you'll see it

Not fixed. Behavior still the same with v1.0.6. Strange things start happen after call of onObjectChange().
to reproduce:

1. create manual entity of any type
2. restart adapter
3. open frontend - at this point everything is Ok
4. Initiate onObjectChange - e.g. change any object in system or even simple open an 'Overview' page in iobroker admin and press ctrl+R (reload of this page changes some system objects and makes lovelace adapter to call onObjectChange )
5. look at WS. you should start receiving two updates of manually created entity. Each onObjectChange will increase the number of WS updates for this entity.

Also, after the steps above, changes made to any controls in frontend are no longer stored.. e.g. try to change anything (turn off light) and reload the page.

Sorry I cannot reproduce your behavior.
May you can deliver me logs with debig level?

here is the log from adapter restart until second update of objects https://pastebin.com/CmnjpkpY
and here is the screen recording, where after first start everything is Ok, but after objects updated second time we start getting duplicated messages: https://photos.app.goo.gl/32MPYSGScRzEkTid9
