title: Swashbuckle.OData doesn't add controller if I change the Entity Set name
body: <p>I have Swashbuckle.OData working with OData (4.0) in an Web Api project. </p>
  
  <p>It's all working fine, but when I change the 'Entity Set' name in the OData config, the OData controller no longer shows up in the swagger JSON file, and consequently the Swagger UI. </p>
  
  <p>This works: builder.EntitySet("AccountRecords");
  This does not work: builder.EntitySet("Records");</p>
  
  <p>Is there something I am doing wrong or missing? How do I 'tell' Swashbuckle.OData that the name is different? </p>
