Make sure Tab was closed and retry if not

[rickd3ckard]

Some tabs still open after public async Task CloseTab(String Id) when spamming the function on 10 tabs in 1 sec
=> save socket address
=> send close http request
=> once done loop through open sockets to check if it's still here with the address
=> try to close again

=> batch test to see if this would solve this bug

Create a clean function that checks for sockets id and compare with tab list and clean.
