Check comment printed before printComment

[fisker]

We check not printed comments,

prettier/src/main/core.js

Lines 43 to 52 in 350f641

	astComments.forEach((comment) => {
	if (!comment.printed) {
	throw new Error(
	'Comment "' +
	comment.value.trim() +
	'" was not printed. Please report this error!'
	);
	}
	delete comment.printed;
	});

I think make sense to prevent comments print multiple times too.

This can prevent #8736 happens.

Turns out this is not easy as I thought, maybe look into it later, closing now.
