Fix doc count mismatch and ._ file filtering in symmetry tests

- Add getprobes() call after ingestion in intanNDR and axonNDR
  make_artifacts tests. getprobes() creates an element document for
  each probe, matching MATLAB's behavior (10 docs instead of 9).
- Remove macOS resource fork files (._*) after extracting the
  downloaded dataset archive in the downloadIngested make_artifacts test.
- Filter ._* files from session summary comparisons in the
  downloadIngested read_artifacts test.
