test(network): fix race in TestNotifier_VariousFlows/Happy_flow (backport of #4502) - #4503

The subtest waited until the receiver callback had run twice and then read the persisted event, expecting two retries. notifyNow increments and writes the retry count only after the callback returns, so on a loaded runner the read could land between the second callback and its write and observe one retry. Same race as fixed for TestNotifier_Notify in #4274; observed on #4487. The subtest now waits for the persisted retry count and checks that the callback ran at least that often.
