Prim2Con overwrites the converved variables which are used in the
evolution to overwrite the primitive again. If now noise is added to the
primitive variables after Prim2Con, this noise is not used in the
evolution and will be overwritten, that is right. This is however not a
problem in GRHydro, just a problem with the schedule of Noise - and this
is what the patch took care of (in addition to the change in the error
message which is also ok).
