FIX getRoot()

[marques-bruno]

Binding was not wrapping BaseNode* into a Sofa.Core.Node()

This means the function getRoot() was not available as is. Correct ?
The error was about : Node::getRoot am I understanding the binding correctly ?

Yeah, the binding was returning a pointer without wrapping it around a pybind11 binding class, thus calling getRoot() would return an unusable pointer.
