Fix some annoyances with the smoketests (#3556)

# Description of Changes

Now running `python -m smoketests` no longer updates
`smoketests/config.toml` with a new identity, and also `replication`
doesn't fail when docker isn't available.

# Expected complexity level and risk

1

# Testing

- [x] those things no longer happen
