Legacy role access remnants after turning on environments

[jameskinneavy]

There is a defect where, if you initially set up a project and save it, but then later turn on environments, the role access for the pre-environment role access persists in the file.

Steps to reproduce

1. Create a new project
2. Add database, schemas, roles, and access
3. Save project
4. Turn on environments
5. Add environments
6. Update access permissions
7. Save project
8. Open yml file in text editor. You will see the pre-environment role access
