[AS3][CodeGenerator] Wrong result after executing Implement interface methods

[SlavaRa]

interface IA {
	public function get v():Function/*(v1:*):int*/ {
		return null;
	}
}

class A implements I|A {
	
}

| - cursor
actual result:

interface IA {
	public function get v():Function/*(v1:*):int*/ {
		return null;
	}
}

class A implements IA {
	
	/* INTERFACE IA */
	
	public function get v():int {
		return _v;
	}
}

expected result:

interface IA {
	public function get v():Function/*(v1:*):int*/ {
		return null;
	}
}

class A implements IA {
	
	/* INTERFACE IA */
	
	public function get v():Function/*(v1:*):int*/ {
		return _v;
	}
}
