Empty Appointments Returns incorrect Response

[kchapple]

@Leo24 If there are no results found in a search, the error should not be 404. The expected result is a Bundle resource with a count of Zero, and a return code of 200, not 404.

For example, when we search for a patient's appointments as in the request below, but the patient has no appointments in the result set, the returned JSON should be a Bundle with a count of Zero.

Actual

Expected

Currently, the response is a non-FHIR complaint error message. If in fact there is an error, then the response should be an OperationOutcome Resource. For example, when we query for a patient by ID, but no patient with that ID exists in the system.
