Generated multi accessor does not support only one service

[h4kuna]

Version: 3.0.12

Hello,

Bug Description

I want create generated multi accessor, but in first moment i add only one service and try to run. I got exception with message
Service '011': Method MMEE\User\MultiMethods::get() must have no parameters. I check both interface and neon, but nothing found. After I add second service, that it works.

Steps To Reproduce

interface MultiAccessor
{
	function get($name): Listener
}

services:
	- App\Model\CacheCleanerAuthSubscriber

	- MultiAccessor(
		sub1: @App\Mode\CacheCleanerAuthSubscriber
	)

Expected Behavior

Works with one service or better message in exception.
