All arguments to 'construct_momentum_element_dg' have been made non-Optional unless they are passed in as Optional in 'construct_momentum_dg', since 'construct_momentum_element_dg' is only called from one place.

Similar changes have been made to 'construct_momentum_interface_dg' except for those arguments that are only needed for the "if(primal)" branch of code.
