fix mapping array of enums to setter which expects array of enums

[MrMeshok]

Fix #269
I found out that this bug was introduced in #230, to be more precise this lines ArrayTransformerFactory.
Before #230 $targetCollections would be equal [] so we would get return new DictionaryTransformer(new CopyTransformer());. And CopyTransformer would just pass enums from property to setPaymentMethods().
But simply removing this lines wouldn't work because they do serve they purpose in fixing weird behavior in #230.

So I dug further and found out original issue.
Here WriteMutator should get that setPaymentMethods() expects PaymentMethod[] but gets blocked here GetTypeTrait because argument $property equals 'setPaymentMethods' and we get this check that result in false and we skip trying to extract types

'$paymentMethods' !== '$setPaymentMethods'
