This fixes the failing tests on MPL2. Two of the tests were failing because of how mpl chooses to do things, which makes me think that the tests are not very robust. My fixes are also rather simple...

For example the test_discrete_colormap_int_levels test, reproduced here:

```python import xarray as xr import matplotlib.pyplot as plt import numpy as np import matplotlib

x = np.arange(start=0, stop=10, step=2) y = np.arange(start=9, stop=-7, step=-3) xy = np.dstack(np.meshgrid(x, y)) distance = np.linalg.norm(xy, axis=2) darray = xr.DataArray(distance, list(zip(('y', 'x'), (y, x))))

darray.plot(levels=7, vmin=4, vmax=8, extend='both') plt.title('mpl {}'.format(matplotlib.version)) ```

produces:
