Changes in this pull request:

• Hardening error response handler to return the correct response status and message from the server when there is an exception converting
• Update decryptErrorResponse to check for content-type before attempting to decrypt (because it's possible that the response is not encrypted)

Testing:

Error Response

• Empty Body
• Hyperwallet Error Response - Content-Type - application/json
• Hyperwallet Encrypted Error Response - Content-Type - application/jose+json
