Timestampable createdAt/By not set when disconnected

[nicooprat]

Hi, thanks for your package, very useful!

When I'm inserting a document client-side while the connection is down (with Meteor.connection.disconnect()), createdAt and createdBy fields are not set. Looks like they're only set on the server, when the app reconnects. I don't understand why though, because I looked into the code and didn't find anything that would cause this behaviour. I tried to create another .before.insert() and it gets called without problem. What am I missing here?

Thanks!
