SAMRAI Regridding makes finer levels in diagnostics inconsistent #400

We're seeing that regridding is occurring with refinemenboxes in during only the first coarsest step, as a result the diagnostic dumps just after the first advance may be contain regridded finer levels, making the coarsened values of the diagnostics inconsistent with coarser level values in diagnostics

AdvanceTest.test_field_coarsening_via_subcycles first step is skipped for now
