We are seeing some test failures for this test in #37291. It looks like
what's going on is that Puma has changed the output for this command
between 4.1 and 4.2

Previously:

```
...
* Environment: development
* Listening on tcp://localhost:3000
...

```

Now:

```
...
* Environment: development
* Listening on tcp://127.0.0.1:3000
* Listening on tcp://[::1]:3000


...

```

So to get around this, instead of checking the binding address, just
check for the presence of 'Listening' generally like we do on server
start.
