fix: prevent removing decorators on classes

[FredericEspiau]

Prevents removing decorators on exported classes that won't be exported anymore

Case

@firstDecorator
@secondDecorator(() => [WithArgument])
export default class C {}
const c = new C();
console.log(c);

Before

class C {}
const c = new C();
console.log(c);

After

@firstDecorator
@secondDecorator(() => [WithArgument])
class C {}
const c = new C();
console.log(c);

Thank you for the patch

[kazushisan]

Suggested change

	throw new Error('Syntaxlist missing');
	throw new Error('sytaxList missing');

or maybe syntax list [nit]

[FredericEspiau]

done

[kazushisan]

Suggested change

	const syntaxList = node?.getChildren()[syntaxListIndex];
	const syntaxList = node.getChildren()[syntaxListIndex];

[FredericEspiau]

good one, done

[kazushisan]

Suggested change

	export class A {}
	const a = new A();
	console.log(a);`,
	export class A {}

can you remove the class instance and console.log from the added test cases to keep it lean?

[FredericEspiau]

ah yes you're right, done
