Schema type incorrectly set when omitted and items given

Schema type incorrectly set when omitted and enums given

Swagger-parser version: 2.0.31

Sample spec:

openapi: 3.0.3
info:
  title: openapi 3.0.3 sample spec
  description: sample spec for testing openapi functionality, built from json schema
    tests for draft6
  version: 0.0.1
paths: {}
components:
  schemas:
    ASchemaGivenForItems:
      items:
        type: integer

When parsing the above schema, type should be unset on ASchemaGivenForItems
When one checks

• ASchemaGivenForItems, the parser incorrectly set type to array when it should remain unset.

Start by reproducing the issue with the OpenAPI sample in the report and inspect how swagger-parser handles a schema with items but no type. Add a regression check showing that ASchemaGivenForItems keeps type unset, then run the relevant parser tests to confirm the correction.
