Bug on ActionClassifier and Moves

[martinezmatias]

Problematic:

The ActionClassifier groups Moves into Root Action moves as done with Insert and Actions (The code is almost the same see here )
However, Moves are different from Inserts/Deletes: a move affects to a Tree, whereas Insert/delects affects to a single node.
This means that, for example, if we move a While, we always only one Move action. But, if we add one While we have N actions (Insert of condition, insert of body, insert of statements inside body, etc).
This means that the classifiers wrongly works when we move element X to element Y, and Y is a leaf of another moved tree Z (Z having more than 1 level). In that case, the classifier produces two roots: mov X and Mov Z.
Note that the behaviour is correct if Z is a single node (and is also leaf i.e. Y )

For example:

method a(){
- call1()
 ....
- if(a){ 
- call2()
- }
}

method b(){
+ if(a){ 
+ call1()
+ call2()
+}
}

Produce two moves: Mov If(a) and Mov call1()

Solutions:

I propose two solutions.

First, I would not group moves. Moved nodes are already grouped, because only the root is marked as moved.
Second, to check in the complete list of parent if there is a moved parent, rather than only in the immediate parent.
