Fix state machine in _DiscoverAvailableFilesTask.perform

* When iterating over folders with folderIterator we must check
elapsed time and decide to exit before we call moveNext. If we
do it in an oposite order we will skip the current element when we
come back - because we will call moveNext again.

* Only add driver.addedFiles *once* to the list of files. Previous
we were adding it everytime we called perform() leading to duplicates
in the list.
