Describe the problem In the latest tag (v0.1.0-alpha.4, at 4f14b5b), a call to lnp-cli create hangs forever after channel creation.

I assume channels get created before the issue arises because of the following log:

[2020-11-04T17:59:58Z INFO  lnp_node::lnpd::runtime] Channel daemon b0459cab9aefa51153067966471c11aa5f6d90ba5233b3b514f0293ff2d22ce2 is registered; total 3 channels are known

and because the channels field in lnp-cli info increases correctly.

However lnp-cli channels still returns an empty string.

To Reproduce Steps to reproduce the behavior:

1. Operating system Debian buster
2. Rust compiler version 1.47.0
3. Did you
   • I set up node in listening mode lnp-cli listen
   • I connected a second node successfully with lnp-cli connect
   • I used lnp-cli create to create a channel between the two nodes

Expected behavior The command line call to lnp-cli create returns after channel creation

Because the channel creation was not finished at that alpha :) It's completed with the next version I used for the demo yesterday

This is fixed since tag v0.1.0-beta.1.
