    Update docs for _destroy_evacuated_instances

    The docstring on this method no longer reflects reality,
    and hasn't since we started filtering on migration records
    starting back in Liberty. This change updates the docstring
    for what the method actually does now, and also includes a
    comment about why we include 'accepted' but not yet complete
    migrations when looking for things to remove from this source
    node.
