Add nested array coercion spec

[braktar]

The coerce seems to be performed correctly, nevertheless, once we want to match the obtained value to the expected type it fails.

Seems related to : #2054

My current assumption is that the type_check provided by the infer_type_check method can't evaluate the returned array of array.

coerced?(coerced_val) returns the following error : "*** TypeError Exception: class or module required"

Some progress here, recursive objects were not recursively verified. The proposed fix works on our side. But i cannot manage to get it working on spec side...

What I notice is that the rack_params returned by the ParamBuilder is flatten
It gives ['a', 'c', 'b'] instead of [['a','c'],['b']]

[[]] returns [[""]] which seems a bit odd.

[['a', { bar: 0 }], ['b']] is currently considered as incorrect, but not for the good reason. It is currently wrong due to the flatten and not because of the hash

Any hint about it ?

The large model returns as expected {"skills_v1":[["vehicule1"]],"skills_v2":[["vehicule1","vehicule2"]]}

Try POSTing JSON in the spec?

If you feel like doing more work, there's a number of issues that have "coercion" in the title that could be in the same code path ;)
