amazonclouddrive: remove unnecessary notifies from DirChangeNotify

Browse Source 
It is unnecessary to notify the node.Parents, because a cahnge event is
generated for all involved files and folders in a move from d1/f1 to
d2/f1. There will be a event for d1, d2 and f1.

Additionally a duplicate notification is resolved when them empty string
is in pathsToClear.

Related to #2006
