Initial testing after enabling file sharing for all organisms

This is some testing I did before any code changes, just after flipping on file sharing (Raw reads) for all organisms.

I was able to attach raw reads to one of the west-nile virus example data by submitting via the web interface using the following directory structure:

➜  scratch tree west_nile_files_submission
west_nile_files_submission
└── test_INYO_2_2011
    └── ERR17072040.fastq.gz

The raw reads file I'm using belongs to one of the west-nile sequences we have on PPX: https://pathoplexus.org/seq/PP_006UYBK.2

I tried this as both the testuser and the superuser, the file gets uploaded to S3 in both cases and registered in the files table:

...and also attached to the submissions in the sequence_entries table:

However, I don't see them getting attached to the submissions in the sequence_entries_preprocessed_data table. Here, I just see the annotation files generated by prepro:

I also don't see them on the sequence details page in the website (presumably because files don't get registered on the processed data entry?)
