Fix MATSHELL support
...
it is conceptually wrong freeing the context in the MatDestroy routine,
since MatDuplicate and MatCopy can be called.
Revert back to use the operator in the context only
This does not happen with PC, since we do not have Duplicate/Copy operations
Provided support for MatCopy

PetscBCHandler: fix for -snes_test_jacobian

PETSc and MFEM have a different approach in handling the Jacobians
...
PETSc reuses the objects, while MFEM usually gives back a new operator each time
When reusing the SNES and TS objects for different simulations,
the matrix type of the underlying DM is never update, nor is the representative matrix
for the DMSHELL (default). This is fine when using AIJ (default mattype in PETSc)
but not when using different types.

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
