Prevent using dangling references in BlackoilModelEbos::updateState.

Browse Source 
Using cachedIntensiveQuantities on parallel grids will cause/is causing
dereferencing a null pointer here. Therefore we resort to iterating over
the grid and using the element Context.

If this turns out ot be performance regression @andlaus owes me a beer!

Closes #1110
