Resolve object style references as simple references

Addresses DiUS/java-faker#148

If the yml contains an object style reference like Address.street_title which doesn't
resolve to a method name on Address, then try 'address.street_title' as a last ditch effort
which is probably how it should be encoded in the yml anyhow.
