[petsc-dev] Could we replace SNESTestJacobian() in maint with that in master?

[Kong, Fande]

To explain me a little better, I added a PR at
https://bitbucket.org/petsc/petsc/pull-requests/1040/fixed-snestestjacobian-in-maint/diff

I just simply copied SNESTestJacobian() in master to maint.

This patch fixed the issues we had in MOOSE.

Thanks,

Fande,
