To Reproduce
Steps to reproduce the behavior:

1. Ensure configs for both auto_create_placeholder_reference_targets and allow_inline_match_url_references are enabled.
2. POST the bundle (see example below)
3. Get back a HAPI-0507 error

Expected behavior

1. The request should be accepted
2. Both the original resource (ex Patient) and the auto-created resource (ex Organization) should be created
