IntelliJ unit test give a different result then Grails unit test

When running Controller unit tests with Grails, they work. When running unit tests with the Junit runner in IntelliJ, they fail. I've debugged the issue, and it seems that in DefaultHtmlRenderer, the 'suffix' field is not populated from the Config.groovy file when running the test in IntelliJ. In Grails however, the suffix is loaded (which is populated with 'Instance'). So, when having a test like:
```
void "Test the create action returns the correct model"() {
when:"The create action is executed"
controller.create()

then:"The model is correctly created"
model.profileInstance!= null
}
```
The code succeeds in Grails, since there is a field called 'profileInstance'. When running the test in IntelliJ, the model is also populated, but then with the field 'profile' (see screenshot).

These are just standard generated tests (by Grails), nothing is added or removed in them.

Reproduce the generated controller unit test with both the Grails runner and IntelliJ's JUnit runner, then inspect DefaultHtmlRenderer and the Config.groovy configuration path. Compare how the suffix is populated in each environment. Done means both runners produce the same model key, including profileInstance.
