Retrieve is not using the pipestatmanager object record_identifier if none is supplied

[donaldcampbelljr]

          Regarding 

why can't retrieve use the class record identifier?

With the above example, psm.retrieve_one("value") , pipestat thinks that value is the record_identifier.

However, if I attempt to specify the arguments, result = psm.retrieve_one(result_identifier="value"), I see that there is a problem and pipestat is not pulling the class record_identifier appropriately.

psm1 = PipestatManager(record_identifier="RECORD1", schema_path="sample_output_schema.yaml", results_file_path="results.yaml", pipeline_type="sample")
psm1.report(values={"number_of_things": 100})
result = psm1.retrieve_one(result_identifier="number_of_things")

Error

  File "/home/drc/PythonProjects/pipestat/opt_dependencies/venv6/lib/python3.10/site-packages/pipestat/pipestat.py", line 708, in retrieve_one
    raise RecordNotFoundError(
pipestat.exceptions.RecordNotFoundError: Results '['number_of_things']' for 'None' not found
