62c304ea48 tests: Allow closed http server in assert_start_raises_init_error (Chun Kuan Lee) Pull request description: The rpc handler may be unregistered when http server haven't been closed yet. So it may be allowable to get -342 `non-JSON HTTP response with \'%i %s\' from server` (503 Service Unavailable) See https://ci.appveyor.com/project/DrahtBot/bitcoin/build/master.2001. It shows "Rejecting request while shutting down" between "RPC stopped" and "Stopped HTTP server" Tree-SHA512: e1f50ab9096cf23494ccc2850c01516c4a75f112c99108759157b22fce2011682a4b88216f206702f6a56e960182c00098053ad75f13aa0eafe27046adae63da
