The docstring seems to imply that it's possible to get in-memory arrays: https://github.com/pydata/xarray/blob/4bb9d9c6df77137f05e85c7cc6508fe7a93dc0e4/xarray/backends/api.py#L732

But it doesn't seem possible because of: https://github.com/pydata/xarray/blob/4bb9d9c6df77137f05e85c7cc6508fe7a93dc0e4/xarray/backends/api.py#L899

This PR removes that or check, changes the default to chunk={}, and fixes the failing tests.
