Error when some assembly metadata tsv files are empty and don't contain accessions to download

[masudermann]

Description of the bug

I am doing some testing of complex_dataset_minimal, and everything starts well, but I'm encountering an error where the pipeline fails if some the tsv files containing the accessions to download for a given family (in my case) are empty. These files are linked from path_surveil_data/assembly_metadata.

Is there a way to just proceed and ignore these empty files?
