Collection agaist schema doesn't support validation correctly for allOf keyword for provided schema.

[VShingala]

In this case (API schema below), the user expects that the test data they pass should be invalid because specificType property value does not contain a grandParentTypeData property. However, Postman reports the data as valid.

Reproduction steps (In app):

• Import the schemas inside Postman
• Generate a collection for them
• Create a mock server for each collection
• Send a request from the generated collections
• See that NO validation issues are shown, even though there should be issues

Reproduction steps (In module):

• Use validateTransaction() API to generate result from API and generated collection from it.
