Potential bug in setting axes for data array (XYZ=ZYX)

Was running into an issue with a particular DataArray where:

```py
mesh = ds.data.pyvista.mesh(x='x', y='y', z='z')
```

and 

```py
mesh = ds.data.pyvista.mesh(x='z', y='y', z='x')
```

were yielding the same result.

This is unexpected and I think the `DataArray` wasn't/isn't being reorder properly
