websockets reconnect after element removed

[goertzenator]

After an element with a ws-connect attribute is removed, the socket connection is closed but then immediately reconnects. If a long lived web page adds and removes many elements with ws-connect, every websocket that ever lived still keeps reconnecting.

This behavior seems to have been added by this commit.

Seems like this was an accident indeed @goertzenator

If you are interested, please feel free to open a PR to fix that, along with a test case so we prevent any future regression!
