Add more testing to dicom archive loader last commit

[cmadjar]

Description

This adds the following tests to test_run_dicom_archive_loader.py:

• test invalid argument provided to the script
• test tarchive_path that does not exist
• test invalid UploadID provided
• addition of some checks post successful run:
  • check mri_upload.number_of_minc_inserted is correct
  • check mri_upload.number_of_minc_created is correct
  • check dicom_archive.session_id has been set
  • check location of the archive after it has been moved to year subfolder
  • check mri_upload.insertion_complete is set to True

It also modifies the DICOMs on the S3 bucket and the entries in the tarchive tables to add the localizer to the T1W to check that the localizer is indeed skipped because it is part of the series to exclude in the configuration setting excluded_series_description.

Replaces #1244 that was polluted by a force-push
