Fix multiple issues on async uploads (not resumable) (#1568)

- general progress bar would not stay on cancelled status because of a set timeout on fnComplete
   removing setTimeout on fnComplete because it is not usefull to do so

 - rm is undefined on async upload (not resumable)
   check rm before assigning pool, this is because self.resumableManager is undefined in that case
   so it would throw an unhandled error
