Title: Apply threshold pressure for all dp

The threshold pressure is applied for all dp.
The sign of the threshold pressure is given by the sign of the dp.

This fix makes a modified SPE 1 where thpress is added match Eclipse results.
This fix also get rids of oscillations in the newton for the Norne model that where introduced when the thpress keyword was added.
