`std::experimental::unexpected<E> try_operation_return_as(std::experimental::expected<T, E>)`

This implementation of try_operation_return_as(expr) returns an unexpected for any expected input. This allows the use of functions returning std::experimental::expected<T, E> in BOOST_OUTCOME_TRY(...).

Requires: Always available.
