Stefano Zampini 4fbe08637c PetscFieldSplitSolver: Remove futile MATNEST requirement 
we can still detect saddle points out of an AIJ or MATIS matrix
Also, field detection may happen trough block size information

Stefano Zampini 03d93d30c2 PetscBCHandler: fix for -snes_test_jacobian 
From the point of view of the solver, I believe the two formulations are equivalent
However,  -snes_test_jacobian tells us we need to zero the time-dependent part
