[list] argument parsing error when using the-bytes flag

[nanjiangshu]

Describe the bug
The command exits with an error when the -bytes flag is placed at the end of the command

Steps to reproduce
The command

/sda-cli  -config s3cmd-gdi.conf  list  -datasets  -url "https://staging-download.gdi.nbis.se"  -byte

returns an error Error: invalid base URL

But this one works

./sda-cli  -config tmp/s3cmd-gdi.conf  list  -datasets  -bytes  -url "https://staging-download.gdi.nbis.se"

and returns the correct result

DatasetID                                	 Files 	 Size
GDID-12345678-11se 	 441 	 1670980823478

Expected behavior

• Arguments of the list command should be parsed correctly
• Tests verifying the fix are added
