Test deployments fixes (paritytech#2057)

* Fix node_impl_version error

```
error: unexpected argument '--node-impl-version' found

  tip: to pass '--node-impl-version' as a value, use '-- --node-impl-version'

Usage: rialto-bridge-node prepare-worker <SOCKET_PATH> <NODE_IMPL_VERSION>

For more information, try '--help'.

```

* Fix rialto-parachain not producing blocks

We must have at least 2 validators for each collator
