Organize tests are failing under pynwb 2.3.0 because test files lack subject_id

[jwodder]

pynwb 2.3.0 was released on the 23rd at 13:33 EST, and the test_organize.py::test_organize_nwb_test_data tests have been failing since because the test files used (from this repository) are no longer recognized as having a subject_id. This seems to have been a last-minute regression, as the dev-deps scheduled test on the 22 did not have this problem.

attn @rly on a possible regression in pynwb 2.3.0.
So it seems to be some behavior change in PyNWB. Do you @jwodder know already that it is something to report to pynwb or it might be some our idiosyncrasy to be fixed in our code?
