Subject: [PATCH] Fix applicable on non naked if for move_guard assist

Example
---
```rust
fn main() {
    match 92 {
        _ => {
            let cond = true;
            $0if cond {
                foo()
            }
        },
        _ => true
    }
}
```

**Before this PR**

```rust
fn main() {
    match 92 {
        _ if cond => foo(),
        _ => true
    }
}
```

**After this PR**
