TS: fix shortcut scaling; document TSComputeIJacobianConstant limitations
The shortcut re-shifting on re-evaluation of the IJacobian can only be used when the implicit system is just the "mass matrix". This re-scaling also needs to be recorded for the next iteration. Since this logic cannot work in general, it is now moved to TSComputeIJacobianConstant. This funtion seems to be of limited use beyond "explicit" finite element computations (especially those that use a consistent mass matrix) and similar.
