GetThetaWorldFrame() doesn't work!!!!

Created by: Elidiano

@adrien-matta If I use for drawing simulation results it doesn't work

on the contrary using the others functions (GetPhiWorldFrame or GetThetaBeamFrame) all work good... (It is not correlated to the new way to transform the momentum from beam to lab frame) it works well also drawing the Theta angle using atan(sqrt(fRC_MomentumX^2+fRC_MomentumY^2)/fRC_MomentumZ)
