Conditional reference while processing transaction bundle

[sridhar-shivraj]

Is your feature request related to a problem? Please describe.
When processing transactions, servers SHALL:
-check all references for search URIs
-For search URIs, use the search to locate matching resources
-if there are no matches, or multiple matches, the transaction fails, and an error is returned to the user
-if there is a single match, the server replaces the search URI with a reference to the matching resource

Describe the solution you'd like
A clear and concise description of what you want to happen.

Describe alternatives you've considered

I just discovered that after switching to FHIR 4.7.1 all of our Synthea-generated data no longer loads. They are all being flagged as invalid because they use conditional references for the Practitioner field. I have disabled validation for our use, but it would be appreciated if this were not necessary by supporting conditional references.

Tested the following cases with a version of the following bundle:

1. Transaction - Create-Patient, Observation with Condition
2. Transaction - Create-Patient, Observation with Condition v1, Observation with Condition v2
3. Transaction - Create-Patient, Observation with Condition - Out of Order

I also worked through the Integration Tests and John is going to update the error message to alert to the not-found reason.
