 Description

No validation when creating a relationship via API

 Steps to Reproduce

1. Log in to the Portal as an admin
2. Go to http://localhost:8080/o/api?endpoint=http://localhost:8080/o/object-admin/v1.0/openapi.json
3. Go to postObjectDefinitionObjectRelationship
4. Set the value of objectDefinitionId to a custom object definition ID
5. Set the Request body to (change the objectDefinitionId1 and objectDefinitionId2):

{
  "deletionType": "cascade",
  "label": {
    "en_US": "Relationship Test"
  },
  "name": "relationshipTest",
  "objectDefinitionId1": same ID from above,
  "objectDefinitionId2": native object definition ID,
  "type": "oneToMany"
}

 Expected Result
The relationship is not created

 Actual Result
The relationship is created even though it is not possible to create a OneToMany relationship with a native object (N-side) via UI

Obs.: Same happens when trying to create a One to One relationship.
