Fix segfault in HttpNetworkLayerTest.GoogleGET when network connection fails.
Fix segfault in HttpNetworkLayerTest.GoogleGET when network connection fails.

This is rather a workaround for the root cause (test touches the network),
but it should not crash anyway.

After this patch the test will fail, not segfault.

TEST=Covered by net_unittest. Check with network connection disabled.
