ui.content fails mvn clean test

### Expected Behaviour
All modules produced by the archetype should have 0 errors when running `mvn clean test`.

### Actual Behaviour
When running `mvn clean test` on the ui.content module, the following error is produced:
``` bash
[ERROR] ValidationViolation: "jackrabbit-filter: Node '/content/dam/wetrain/jcr:content/folderThumbnail' is not contained in any of the filter rules", filePath=src/main/content/jcr_root/content/dam/wetrain/_jcr_content/folderThumbnail

### Reproduce Scenario (including but not limited to)
Create a project using the latest archetype (36) and then on the project root or in the ui.content module run
``` bash
mvn clean test
```

#### Potential Solution
Delete the `src/main/content/jcr_root/content/dam/wetrain/_jcr_content` folder from the archetype creation, it's not needed.

Reproduce the failure by creating a project with archetype 36 and running `mvn clean test` from the project root or `ui.content`. Inspect `src/main/content/jcr_root/content/dam/wetrain/_jcr_content` and the reported validation violation; done means the generated `ui.content` module passes `mvn clean test` with no errors.
