The sync engine rely on the 'M' in premission to ask for confirmation (As requested in issue #5340) But we only want to ask the premission for the 'root' of the mounting point and not for every subfolders within it. So we change the discovery phase in a way that it does not keep the 'M' for children within the external storage.
