ObjectTypeDefinition to InterfaceTypeDefinition creates error even if the fields are the same

[gabsima-nexapp]

Describe the bug

An error occurs when generating diff between 2 schema when a response changes from an ObjectTypeDefinition to an InterfaceTypeDefinition even if both response contains the exact same fields. The graphql query we made before and after the change on this response worked as expected. This should not be an error.

To Reproduce
Steps to reproduce the behavior:

1. Generate a schema with a graphql response containing an ObjectTypeDefinition
2. Generate the same schema changing the response to an InterfaceTypeDefinition with the exact same fields
3. Generate a diff using this tool
4. An error is reported by the tool
   

Expected behavior

No error should be reported if the change does not impact any queries made before the newest change.

Environment:

• OS: Debian GNU/Linux
• @graphql-inspector/...: 2.3.0
• graphql: 1.3.72
• NodeJS: v12.19.0
