fix: MultiReturn unpacking with get accessors is broken

[Z3rio]

Introduction / Explenation

Upon running the example below, you'll quickly realize that the getter function errors, whereas the normal function does not.
Even though they consist of the same code.

The issue seems to be with unwrapping return values in class getters.

What should happen instead?

I think most of us would simply expect both these code snippets to work the exact same, aka to unwrap the return values without any issues.

Reproduction

Code

class TestClass {
  public get Test1(): LuaMultiReturn<[number, number]>{
    return $multi(0, 0);
  }

  public Test2(): LuaMultiReturn<[number, number]>{
    return $multi(0, 0);
  }

  public showcaseIssue(): void {
    const [a, b] = this.Test2();
    console.log(a,b)
    const [c, d] = this.Test1;
    console.log(c,d)
  }
}

const a = new TestClass();
a.showcaseIssue()
