rs-af panics on start

[Varunram]

With recent merges, rs-af hasn't been updated and hence errors out when we try to start it:

It prints addr: localhost, port 12345 after exiting, which might be a good place to start for those willing to take up this issue. I speculate the issue isn't much, but I'm not a rust expert and @delbonis might have a better estimate.

Did you run lit with --unauthrpc? It requires that since I didn't want to reimplement lndc. You also would have to specify the ports properly since 12345 isn't the default. See --help.

yeah, rs-af opens, shows the channels grid and then prints out the blue screen as above.

Oh weird, I'll look into it.
