ASB v0.10.1 Not re-registering with Rendezvous node
**Describe the bug**
We run a rendezvous node, and while in our logs wee see that we have a few users adding their ASB to our rendezvous, after a few hours the node expires and never renews. With rendezvous v0.1.0, we noticed a re-registering of the nodes after expiry. Not sure if this is with ASB or rendezvous v0.2.0, so I'm posting here

As such, after a few hours a `list-sellers --rendezvous-point ...` returns no Market Makers. 

**Lost/trapped Funds**
No

**Debug logs**
I've obscured the actual nodes connecting except the last one which is mine as a test. 

```shell
$ sudo journalctl -f -u rendezvous
