Mirroring seems to fail because of some null / string comparisons in CacheProviderMongoDB.cs

I'm not much of a C# developer so there's probably a better way to do this, but this seems to get it syncing if you want a PR

Hi, yes go ahead an submit a PR please, we haven't been using the mirroring recently while we are on temporary servers so that's probably why it hasn't been a problem for us.
