Enable scene checking when launching through python (#616)

* Add scene checking before initRoot when scenechekcing is available

* Update bindings/Sofa/src/SofaPython3/Sofa/Simulation/Submodule_Simulation.cpp

Co-authored-by: Frederick Roy <fredroy@users.noreply.github.com>

* fix typo

* fix typo again

* Add boolean to deactivate scene check
