Fix DefaultOvsdbClient Class's getBridges's improper return value

When tableStore or rowStore is null, getBridges() should not return (null),
that will cause NullPointerException in its two usages:

1. OvsdbBridgeConfig.java, line 113-115:

        Set<OvsdbBridge> bridges = client.getBridges();
        return bridges.stream()......

2. OvsdbControllerConfig.java, line 92:

	.filter(cs ->
	 cs.getBridges().stream()
	.anyMatch(b -> dpidMatches(b, ofDeviceId)))
	......
