Restore broken test_basic_csr_directed_graph

Works around invalidation of bundle property maps (see #373).

The `#if SEHE_UNSTABLE_PROPERTY_MAPS_FIXED` section is there to signal
my intent to investigate a generalized fix under that issue. It doubles
as literate documentation of the need for the workaround, so it's less
likely to bite the unwary.
