Misspelled properties with two leading underscores get an incorrect suggestion with an extra underscore at the beginning

```ts
export declare let a: {
    __foo: 10,
}
    
a.___foo
```

Expected:
```
Property '___foo' does not exist on type '{ __foo: 10; }'. Did you mean '__foo'?
```
Actual:
```
Property '___foo' does not exist on type '{ __foo: 10; }'. Did you mean '___foo'?
```
