Proposed changes

There is a small bug in the timer implementation. If the timer is leading, it can resolve the timer immediately. When it does this, it clears the _timeoutId and _mainTimeoutId, but since if was resolved immediately, the _mainTimeoutId is not created yet.

So, the timeout resolves and always creates a 5 seconds timer which hangs the process. This is especially visible when browser.deleteSession is called.

I debugged this using the same reproduction from #14639, but called destroySession at the end. I expect the process to stop immediately after the promise is resolved, but I always need to wait 5 seconds because the url method started a timeout, but never cleared it.
