typo in PreintegrationBase.cpp?

Hello

I am not sure I understand what the whole function is doing, but that H2 || H2 looks like a typo to me (H1 and H2 are OptionalJacobian):

gtsam/gtsam/navigation/PreintegrationBase.cpp

Lines 130 to 132 in 4abef92

    
           NavState state_j = state_i.retract(xi, 
        
                                              H1 ? &D_predict_state : nullptr, 
        
                                              H2 || H2 ? &D_predict_delta : nullptr);

Is it supposed to be H1 || H2?

Indeed looks like a typo, do you want to make a PR to fix this?

	NavState state_j = state_i.retract(xi,
	H1 ? &D_predict_state : nullptr,
	H2 \|\| H2 ? &D_predict_delta : nullptr);
