No timeout error when timing out due to restart: true

Testing #3238

While successfully debugging using restart: true and nodemon, I created a syntax error and waited. The debugger eventually stopped attempting to connect after 10 seconds. There was no UI error indicating what happened. The console did have errors though.

Note that the error does appear on an initial failed attach attempt:

@isidorn I've debugged this and it seems that errors returned from 'attach' are only shown in the UI if it is the first 'attach' and not a restarted 'attach'. I tried to find a 'filter' in your code that prevents these error from being shown, but I wasn't successful. Do you have an idea why these errors are not showing up?
