Class properties should be initialized after constructor parameter properties

Input:
```ts
class Test {
  public foo = this.bar;
  constructor(public bar: string) {}
}
```

Current Result:
```lua
-- ...
function Test.prototype.____constructor(self, bar)
    self.foo = self.bar
    self.bar = bar
end
```

Expected Result:
```lua
-- ...
function Test.prototype.____constructor(self, bar)
    self.bar = bar
    self.foo = self.bar
end
```
