MPU tests are out of sync with Muskie master branch implementation

[jordanhendricks]

In an earlier version of the MPU implementation in muskie, which was deployed as a feature branch image, only two possible states were returned from get-mpu: created and finalizing. This was inconsistent with the original design, which included a third state: done. The mmpu tool was integrated prior to the MPU changes in muskie's master branch, but the node-manta tests were not updated after muskie was changed to reflect the initial design. As a result, the mmpu tests and client tests that commit and abort uploads (then verify as such by doing an mpu-get) will fail with the incorrect state.

This results in errors that look like the following:

✖ commit upload

The tests need to be updated to match what is in muskie's master branch for MPU.
