Example
---
```rust
//- minicore:bool_impl
fn main() {
    true.t$0hen(|| 3).unwrap_or_else(|| 4)
}
```

Old output:

```rust
//- minicore:bool_impl
fn main() {
    if true {
        Some(3)
    } else {
        None
    }.unwrap_or_else(|| 4)
}
```

This PR current output:

```rust
//- minicore:bool_impl
fn main() {
    if true {
        3
    } else {
        4
    }
}
```
