BidomainVentricles: dubious extracellular_potential output
Test suite fails when checking the results: the extracellular potential doesn't match the one put in ExpectedResults.
There is something fishy here: the output is not the same in sequential and parallel, so there is definitely something wrong in its computation (same works seamlessly for SurfacicBidomain).
If extracellular is commented test suite is ok - so transcellular_potential seems to be computed correctly.
