fix crash when attempting at add nil tileSource #88

Does what it says on the tin. I've seen this sort of thing in relation to something like this where a network-fetch-based tile source comes back empty. While this is developer error for not providing an online/offline check and/or alternative layer, avoiding a crash would be nice, too.
