Test failure with dask

Packaging xarray 0.10.4 fails on Debian (where 0.10.3 succeeds).

```python ___ TestDataArrayAndDataset.test_dot ___

args = ('...ab,...b->...a', dask.array<array, shape=(4, 6), dtype=float64, chunksize=(2, 2)>, dask.array<getitem, shape=(6,), dtype=float64, chunksize=(2,)>) kwargs = {} dispatch_args = (dask.array<array, shape=(4, 6), dtype=float64, chunksize=(2, 2)>, dask.array<getitem, shape=(6,), dtype=float64, chunksize=(2,)>)

def f(*args, **kwargs):
    if list_of_args:
        dispatch_args = args[0]
    else:
        dispatch_args = args[array_args]
    if any(isinstance(a, dask_array.Array) for a in dispatch_args):
        try:

          wrapped = getattr(dask_module, name)

E AttributeError: module 'dask.array' has no attribute 'einsum'

xarray/core/duck_array_ops.py:48: AttributeError

```
