Describe the bug
ProtocolLibrary.getProtocolManager() returns null.

To Reproduce

1. Use ProtocolLibrary.getProtocolManager() on plugin onEnable()
2. See error when trying to add a listener because ProtocolLibrary.getProtocolManager() is null.
   Cannot invoke "com.comphenix.protocol.ProtocolManager.addPacketListener(com.comphenix.protocol.events.PacketListener)" because the return value of "com.comphenix.protocol.ProtocolLibrary.getProtocolManager()" is null

Yes the plugin has ProtocolLib as a dependency and loads after ProtocolLib.

Expected behavior
ProtocolLib setup the protocol manager.
