Title: Allow for variance in netCDF4 behaviour.

Before 1.0.8 netCDF4 returned a MaskedArray for the variables in this test file. Since 1.0.8 it returns a plain ndarray. Since this test is focussed on cell methods and doesn't care about the data values at all this PR just normalises to MaskedArray.
