Fix severe bug when calling adaptivity algorithm
Time parameter has to be the conclusion time of the last time step. [ci skip] because this branch has the old testing scheme

I have never understood why this method is adapting the grid before it writes the computed solution. Becuase what I understand is that it is printing the old solution in the new grid view. It should work, but it must be wasting unnecessary space. @lriedel is there another logical explanation or something I don't get here?

We don't plot the results of the error estimator. If we plot the solution first and then adapt, the adaptation becomes visible in the output of the next step, which makes it harder to determine the features of the solution that caused local adaptations. You're right, we plot the projection of the old solution on the adapted grid. Notice that it's not necessarily wasting space because adaptivity can also coarsen the grid.
