Describe the bug

Attempting to override the classification of all operations from an OpenAPI handler from Mutation to Query results in an invalid schema - reports as Type Mutation must define one or more fields.

As long as there is at least one mutation left, this works as expected, but removing all mutations results in this error.

To Reproduce
Steps to reproduce the behavior:

Add an openapi handler that contains queries and mutations, and re-classify all mutations to queries e.g.

        selectQueryOrMutationField:
            - fieldName: 'searchLocation'
              type: Query

Expected behavior

Similar to #1474 the Mutation field should be removed if there are no mutations left after reclassification.

Environment:

• OS: macos
• @graphql-mesh/openapi: 0.33.39
• NodeJS: 16.18.0
