Fix a crash when undo/redo a creation of a selection mask

There were several architectural fixes needed:

1. KisAnimationCurveChannelListModel stores an internal list of selected nodes (dummies), therefore it should also be subscribed to sigBeginRemoveDummy() signal to update this list before the dummy will be actually deleted.

2. KisNodeManager should not allow activating a node if it is not visible in the layers docker (KisNodeModel). To move the "model" part of node hiding into KisNodeManager without making all the internal classes depend on it a special class KisNodeDisplayModeAdapter was introduced.
