Circular bean dependency

[Sean McIlvenna]

I'm trying to upgrade my fork of hapi-fhir-jpaserver-starter to 5.7 (to start with).. I'm getting the following error:

```

Description:

The dependencies of some of the beans in the application context form a cycle:

┌──->──┐
|  fhirServerConfigR4 (field private ca.uhn.fhir.jpa.api.dao.DaoRegistry ca.uhn.fhir.jpa.config.BaseConfig.myDaoRegistry)
└──<-──┘


Action:

Relying upon circular references is discouraged and they are prohibited by default. Update your application to remove the dependency cycle between beans. As a last resort, it may be possible to break the cycle automatically by setting spring.main.allow-circular-references to true.

Disconnected from the target VM, address: '127.0.0.1:51804', transport: 'socket'

Process finished with exit code 1

```

Can anyone point me in the right direction? I've been staring at this, not figuring it out... Thanks in advance!
