The bootstrap is interrupted without any errors if the process becomes ready when already bootstrapping

At least form last year when we switched to 102 (and Clang for almost everything!), I've seen the bootstrap on Windows fail without a real cause.

I don't know if I've never thought to check the logs before a week ago, but now I did and they contain this when it happens:

I was about to open an issue on little-t-tor, but I think we can investigate a little bit more on our end, first.

At least so that we can give the netteam more context for this.

In particular, I think we should find if we're calling DisableNetwork and why.

It might be that we're misinterpreting a bootstrap notification, and move back in the TorConnect state machine (or, maybe, we're going back to the Configure state for any other reason).

I don't do anything special to make this appear, but it happens quite randomly (not always), and I think it's quite easy to encounter it.
