Applying automatic code transformation for "guard clause critic" removes method comment

[juliendelplanque]

When I apply the automatic code transformation for "guard clause critic", it removes method comment.

Here is how to reproduce the issue:

1. Create DummyObject class
2. Add #methodToRefactorWithGuardClause method with source code:

methodToRefactorWithGuardClause
	"This comment will be removed by refactoring engine."
	1 + 1 = 2
		ifTrue: [ 
			'Hello' inspect.
			'world' inspect ].

This method will show the quality assistant critic "Replace single branch conditional with guard clause".

If you click the automatic repair button of the critic, it correctly transform the code but removes the class comment leading to the following method:

methodToRefactorWithGuardClause
	1 + 1 = 2
		ifFalse: [ ^ self ].
	'Hello' inspect.
	'world' inspect
