Initial fix for apiEnableAction() and ApiProblem usage

This doesn't fix all problems.  There is still the problem of this for success in the action:

```
Fatal error: Cannot use object of type ZF\Apigility\Admin\Model\ModuleEntity as array in /Users/ralphschindler/Projects/my-project/vendor/zfcampus/zf-apigility-admin/Module.php on line 379
```
