I apparently have a bad habit of prepending my s3 strings with 's3://' (see #2740)

To reproduce:

```python import numpy as np import xarray as xr import s3fs s3 = s3fs.S3FileSystem(**options) store = s3fs.S3Map(root='bucket/store.zarr', s3=s3)

Create and write

a = xr.DataArray(np.random.randn(2, 3)) a.to_dataset(name='data').to_zarr(store)

Read back in

a = xr.open_zarr(store) print(a) Actual Result: <xarray.Dataset> Dimensions: () Data variables: empty `` Expected Result: my dataset, which I can then get the DataArray witha['data']`

If the 's3://' is not there everything works as expected.

I will add that the fact that it at least opens now means I believe we can close #2740.

xarray version 0.12.1 zarr version 2.3.1 s3fs version 0.2.1
