Subject: [PATCH] fix(mega): use newest file for same filename (#8422 close
 #8344)

Mega supports duplicate names but alist does not support.
In `List()` method, driver will return multiple files with same name.
That makes alist to use oldest version file for listing/downloading.
So it is necessary to filter old same name files in a folder.
After fixes, all CRUD work normally.
