Change Description

I decided to investigate on a bug we've had for a long time.

The bootstrap is interrupted (especially on Windows, but I use a VM) without any explanation.

The issue is that TorConnect might receive a notification when its state has already changed from the initial one. In particular, if it goes from Bootstrapping to Configuring, it also makes the bootstrap stop (set DisableNetwork=1).

My solution is to ignore this notification if we aren't in the initial state anymore.

A consideration to do is that the settings topic we're ignoring is notified when we've set the configuration from browser preferences to torrc. However, the settings from the previous session should already be in the torrc, and any other change should have already been saved, and I don't think we need to cycle a disable network to apply them in any case.

The alternative is to rework the UX, but I don't think it's really needed in this case.

See also my comments on the related issue.

Since this bug is only a bit annoying, I think it's fine to keep it in alpha for a while, especially since we're not doing many of them, without backporting it.
