Review comment:
PR #4537 aimed to allow previous functionality to work as it did in
previous versions of NiFi. However, the resolution order changed to also
address NIFI-7635. In that PR, the `resolvedValue` was determined in this order:
- configuredValue
- default value from the ComponentNode
- default value from the PropertyDescriptor
Whereas in earlier versions of NiFi (pre 1.12.0), the resolution was done in
this order:
- configuredValue
- default value from the PropertyDescriptor
- default value from the ComponentNode
