* ni models did not inherit from their non-ni base models,
  thus the wrong local residual and fluxvars were used (navierstokes)

Feature/improve flux over surface

See merge request !1495

* treat fluxes over boundaries properly (Neumann fluxes
  were not considered before)

* simplify volume flux calculation: just use v * A
