When a download is canceled, it goes through a state that looks very much like a paused download (ie, the transfer has been canceled but we haven't yet removed the partial data ffrom disk).
As a result, we generate multiple onChanged events, one in which paused and canResume go from false to true, then a second in which those fields go back from true to false and error goes to USER_CANCELED.
Note that there are multiple ways a download can be canceled, and we'll want to make sure we catch all of them, including Download.finalize() [1] as well as via the UI [2]
