Short description of error
Keyframed node properties stay linked after shading network duplication

Exact steps for others to reproduce the error
If I duplicate from the properties panel a shader that as animated nodes, those animated nodes are linked in some way by their keyframes : if I move or delete a keyframe on the base shader, it moves or delete it also on the duplicated shader, althought I can change node properties that are not keyed. You'll find a test file showing the bug, the animation is on the color mix node. Just move or delete a keyframe on the animation.

Confirmed.
Seems another issue with data path resolution on nodes [I dont remember the details, but I do recall there were issues relating to this (nodes and drivers e.g.)]

Also note that renaming a node will break the animation actually (was not the case in 2.79)

@Joshua Leung (aligorith): mind sharing your wisdom?
or maybe @Jacques Lucke (JacquesLucke) has an idea?
