pytest: fix flake due to cln-grpc starting before "public key" message.

Browse source 
e.g.
```
lightningd-1: 2022-03-28T11:02:12.476Z DEBUG   plugin-cln-grpc: add_pem_file processed 1 valid and 0 invalid certs
lightningd-1: 2022-03-28T11:02:12.478Z DEBUG   plugin-cln-grpc: Connecting to \"lightning-rpc\" and serving grpc on 0.0.0.0:36331
lightningd-1: 2022-03-28T11:02:12.478Z DEBUG   connectd: REPLY WIRE_CONNECTD_ACTIVATE_REPLY with 0 fds
lightningd-1: 2022-03-28T11:02:12.478Z INFO    lightningd: --------------------------------------------------
lightningd-1: 2022-03-28T11:02:12.478Z INFO    lightningd: Server started with public key
```

Which means we don't see it, since start() swallows it:

```
>               raise TimeoutError('Unable to find "{}" in logs.'.format(exs))
E               TimeoutError: Unable to find "[re.compile('serving grpc on 0.0.0.0:')]" in logs.
```
