Subject: [PATCH] Fix "Not a string" Map Conversion spam
The maps did convert successfully, but had noisy logs due to Spigot
implementing this logic incorrectly.
This stops the spam by converting the old format to new before
requesting the world.
Track spigot issue to see when fixed: https://hub.spigotmc.org/jira/browse/SPIGOT-6181
