[cleanup] Fix deprecation warning being emitted always

Fixes #1447 (closed)

Notes for the reviewer

If, for example, I add the patch

diff --git a/dumux/porousmediumflow/immiscible/localresidual.hh b/dumux/porousmediumflow/immiscible/localresidual.hh

I get a deprecation warning for 1p_incompressible_box_numdiff otherwise not.
