Emit an incomplete event when maxRetries is exceeded

[yamsellem]

If a part failed to be uploaded, a failed event is emitted.
Then a new upload is launched for this part until maxRetries is reached.

But, if every uploads of a part fail, the complete event is trigger anyway.
This event is misleading, because the full upload is done, but the file is incomplete.
For example, if there is only one part, the complete event will be triggered with a size of 0.

Replacing this event by done and triggering an incomplete event make more sense.
