Nope, it will always use the hostname.
This is not as stupid as it seems, because this connection is used for
replication.
So it wants to make sure it is able to connect to itself through the
same means as its peers would, so this is quite acceptable.

You would think I should just open up the firewall for replication
stuff, but in my case (development laptop, mimicking production env)
these are all on the local machine and I don't want others to connect
to it.

So I guess this is a bit of an edge-case. Clearly, using the external
interface is what mongo should do here.
It's just my strange everything-local setup and firewalling needs that
get me in trouble.
I just added 127.0.0.2 as my hostname to networking.extraHosts for now
to get the old behaviour back, as I can't think of any other solution.
