can't ls the root of a bucket? #52
Description
I'm having trouble ls'ing the root of a bucket. might be a boto/botocore issue. the problem is that os.path.normpath turns '' into '.', and then botocore barfs.
for ref, boto is version 2.42.0, botocore is version 1.7.43. python 3.

ClientError: An error occurred (XMinioInvalidResourceName) when calling the ListObjects operation: Resource name contains bad components such as ".." or ".".also, related, running cci.ls with no arguments, which seems like it should ls the bucket root, just barfs because the decorator expects an argument:

if that's intended behavior, fine.
