Since we added special handling for the case for rho[2] < 0, the bulk of CorrectJacobian is pointless in the common case. So add a simple one dimensional loop which rescales the Jacobian. This speeds up this method immensely. The robustification of a Jacobian gets speeded up by > 50%. Change-Id: I97c4e897ccbb5521c053e1fb931c5d0d32f542c7
