injecting concepts should also inject a vocabulary object with concept_id

[barabo]

Each vocabulary should map to a vocabulary.concept_id, which can be injected along with concept.

This is needed in classes like AllergyIntolerance and Encounter for columns like condition_source_concept_id.

For example, this coding should go from this:

...
  "code": {
    "coding": [
      {
        "system": "http://snomed.info/sct",
        "code": "232347008",
        "display": "Dander (animal) allergy"
      }
    ],
    "text": "Dander (animal) allergy"
  },
...

To this:

...
  "code": {
    "coding": [
      {
        "system": "http://snomed.info/sct",
        "code": "232347008",
        "display": "Dander (animal) allergy",
        "concept": {
...
        },
        "vocabulary": {
          "vocabulary_concept_id": 44819097,
          "vocabulary_id": "SNOMED"
        }
      }
    ],
    "text": "Dander (animal) allergy"
  },
...
