dont use auto generated plan when both yes and plan options used

[tongueroo]

This is a 🐞 bug fix.

• I've added tests (if it's a bug, feature or enhancement)
• I've adjusted the documentation (if it's a feature or enhancement)
• The test suite passes (run bundle exec rspec to verify this)

Summary

Make sure to use the provided plan when both the --plan and --yes options are used.
