Filter MedicationRequest Retrieves on status

[sliver007]

Need to be able to filter MedicationRequest retrieves by status (to 'active'), but it doesn't seem to work. This is specifically relevant in the three main queries of OpioidCDSCommon

An example pattern:

codesystem "Medication Request Status Codes": 'http://hl7.org/fhir/medication-request-status'
code "Active MedicationRequest": 'active' from "Medication Request Status Codes"
("Get Active Ambulatory Medication Requests"([MedicationRequest: status in "Active MedicationRequest"])) Rx

The status filter depends on a change in the 1.2.1 evaluator and so can't really be implemented until the Ruler is updated to take that as a dependency.
