Fail to download recursive with encryption

[erikogabrielsson]

Describe the bug
Running download with the recursive and pubkey flags fails with:
Error: failed to get file for download, reason: server returned status 404

Steps to reproduce
Run command:
./sda-cli.exe download -config .\s3cmd.conf -dataset-id -url https://download.bp.nbis.se -pubkey test.pub.pem -recursive

Expected behavior

• Recursive download works with encryption.
• Tests verifying the fix are added

Additional context
Using the getFileIDURL() method in the fileCase() method looks to solve this issue.

Estimation of size: small

Estimation of priority: low

This is not a bug but rather a missing feature since the recursive download with encryption is not implemented yet, see #496 .

Meanwhile, one can use:

sda-cli download --config <s3config-file> --url <download-url> --pubkey <pubkey-filepath> --dataset-id <dataset-id> --outdir <outdir-name> --from-file <filelist>

with a filepath list from results fetched using sda-cli list to achieve the same result.
