Issue: #657
Turns out the bug is more general, and not limited to arrays of enums.
In the case of array schemas, the constraints of the array elements were being attached to the array itself when generating the OpenAPI descriptions.
This is fixed by not extracting validators out of CollectionElements validator when the schema is equal to SArray, and extracting all validators otherwise. Added an additional test that validates an array of ints to prove the solution.
