Adds an integration test for conservative transport, which tests consistency and conservation for three configurations of rho_d and m_X: Same space (both in DG) order 1, different spaces (rho_d in DG, m_X in theta) for orders 0 and 1.
Also, fixed some bugs in the wrapper.py script with the implementation of the conservative versions of the EmbeddedDG and Recovery wrappers.
