    Summary: Dangling reference in `access::Map` with Constant

    Details: Using the `arc_swap::access::Map` with the `Constant` test helper (or with user-provided implementation of the `Access` trait) could sometimes lead to the map returning dangling references. Replaced by implementation without `unsafe`, at the cost of added `Clone` bound on the closure and small penalty on performance.
