* accounts/keystore: add timeout to test to prevent failure on travis The TestWalletNotifications test sporadically fails on travis. This is because we shutdown the event collection before all events are received. Adding a small timeout (10 milliseconds) allows the collector to be scheduled and to consume all pending events before we shut it down. * accounts/keystore: added newlines back in * accounts/keystore: properly fix the walletNotifications test
