Tor Browser Bundle spawns the Tor process and listens on port 9150, it doesn't randomly pick a port.

Seems like there are a lot of advertised testnet HS nodes that
don't actually work. Lack of the testnet port on the example
HS config might be one reason.
I've seen users confused multiple times thinking they
should be using -tor to set their tor proxy and then
finding in horror that they were still connecting to
the IPv4 internet.
Even Jeff guesses wrong about what the knob does, so
I think we should rename it. This leaves the old
knob working, we can pull it out completely in a
later release.
