Preserve step queue during reconnect #5126

  1. fix(sync): preserve queue if sendRemainingSteps fails 

    During a network disconnect
Yjs-websocket notices missing awareness messages and closes the connection.
In this case the remaining steps can also not be send out and the request fails.
Preserve the queue so we can use it once the network is back up.

  2. fix(sync): keep queue around during reconnects 

    When yjs does not receive awareness updates
it will close and reopen the websocket.
Keep the content of the queue, i.e. the outgoing steps
so they can be send out once the connection is back.

  3. fix(sync): ensure queue stays the same array 

    Change the content of `queue` with `queue.splice`
rather than setting `queue` to another array.

  4. fix(sync): only clear queue after successful send 

    Also add a unit test for the websocket polyfill

  5. fix(sync): clear old providers on reconnect 

    avoids the old provider leaking error events.
