problem when uploading file with no object name

[alexhuth]

Uploading a file without specifying the object_name throws an error. Not sure if this is python3 specific, and I could probably fix it but I'm on a time crunch, so I thought I'd at least post it.

In [13]: cci.upload_from_file('stuff.tar.gz')

TypeError: expected string or bytes-like object

I think the problem is that object_name is None, making the re.sub function barf.
