@aliaksei-chareshneu : no chunks (i.e. no data) should be loaded at this point. Only _metadata_ about how chunks there are, where they are located, etc.

Build showing various errors (though not the specific one from #844): ``` FAILED zarr/tests/test_core.py::TestArrayWithN5FSStore::test_nchunks_initialized FAILED zarr/tests/test_core.py::TestArrayWithCustomMapping::test_nbytes_stored FAILED zarr/tests/test_core.py::TestArrayWithFSStorePartialRead::test_append_2d FAILED zarr/tests/test_core.py::TestArrayWithFSStorePartialRead::test_append_2d_axis FAILED zarr/tests/test_core.py::TestArrayWithFSStorePartialRead::test_array_1d FAILED zarr/tests/test_core.py::TestArrayWithFSStorePartialRead::test_array_1d_fill_value FAILED zarr/tests/test_core.py::TestArrayWithFSStorePartialRead::test_array_1d_selections FAILED zarr/tests/test_core.py::TestArrayWithFSStorePartialRead::test_array_2d FAILED zarr/tests/test_core.py::TestArrayWithFSStorePartialRead::test_array_2d_edge_case...
