Title: HighLine::String should not be serialized in ey.yml

I noticed that the `migration_command` got serialized as a highline string when migrating to v2.0.1

```yaml
---
environments:
app_production:
migration_command: !str:HighLine::String rake db:migrate
migrate: true
branch: master
```

This breaks deployment. Fixed it in a general way for stings fetched via `HighLine.new.ask`.
