Execution can enter the lambda in NetworkResourceLoader::retrieveCacheEntry, without there being much indication of which exit point was taken. If flow enters into startNetworkLoad, we'll get some logging from that function, but not from the others. Add some logging so that we know what the result was from looking up the resource in the cache. Having this logging would have helped in the tracking down of situations where we see in the logs that a resource is starting to be loaded but then there's no logging saying what ultimately happened to it.
