GET /entities API Returns Empty Array

Unlike other endpoints included in Symbl.ai Conversation API (Action Items, Follow-Ups, Topics, Questions, etc.) Entities require an additional parameter to be included in the initial submission in order to be enabled.  

Regardless of if the initial submission is generated with Telephony, Streaming, or Async API the parameter {"detectEntities": true} must be passed in the request in order for Entities to be processed and viewed from the Conversation API 

For example, suppose a conversation was submitted through Async Audio URL.  If the request does not include the "detectEntities" parameter, Entities will not be generated.  The response to GET /entities will return a status 200, with an empty Entities object.
