Motivation: `testClientBindWorksOnSocketsBoundToEitherIPv4OrIPv6Only` would fail sometimes leaking the IPv4 promise in `GetaddrinfoResolver` `HappyEyeballsConnector` returns the connection when it resolves either IPv4 of IPv6. It uses the `GetaddrinfoResolver` which holds a promise for each of the IPv4 and IPv6 resolution; when one is completed it is possible to start tearing down the test and shutting down the event loop before the other is completed and we leak the promise. Modifications: Complete both futures on the event loop rather than the dispatch queue. Result: The futures are completed in the same event loop tick meaning that we cannot continue execution and leak one.
