mmpu parts threw "AssertError: path (string) is required" for a committed upload

[askfongjojo]

I have a simple one-part upload and did a mmpu parts before/after committing it:

[root@base64-16-4-1 ~]# mmpu parts $uid
/angela.fong/uploads/e6b/e6b61194-5a41-c2ff-8895-f3f88d6d3103/0

[root@base64-16-4-1 ~]# mmpu commit $uid 4b7b28b4-a707-4997-b9b3-a8791a19c221

[root@base64-16-4-1 ~]# mmpu parts $uid
mmpu: AssertionError: path (string) is required

The commit itself was successful. If the parts command is not meant to be used for committed uploads, it'll be better to return an explicit error than throw an assertion error.
