DEFECT: Edits to enviroment settings get saved even if you click CANCEL

When you open the environment editor and make any changes, but then click the Enviroment editor's Cancel button, any changes that you made should be forgotten.

However, the changes all get saved anyway.

This appears to affect all versions of Ready API! Pro.

Reproduce:

1. In a project with an enviroment, click the Enviroment button

2. Make some edit (e.g. edit one of your custom properties, or a service endpoint)

3. Click the Enviroments Cancel button

4. Re-open the environment editor and look at the items that you had edited

Result:  Notice that your edits got saved, even though you canceled.
