Client commands appear in command block suggestions

[haykam821]

A command registered to the client command dispatcher is still shown within the suggestions for a command block, most likely because of a mixin that affects all uses of the server command dispatcher even in situations where client commands are not applicable:

	// Add the commands to the vanilla dispatcher for completion.
	// It's done here because both the server and the client commands have
	// to be in the same dispatcher and completion results.
	ClientCommandInternals.addCommands((CommandDispatcher) commandDispatcher, (FabricClientCommandSource) commandSource);
