Tweak conditions for E0026 and E0769

When we have a tuple struct used with struct we don't want to suggest using
the (valid) struct syntax with numeric field names. Instead we want to
suggest the expected syntax.

Given

```rust
fn main() {
    match MyOption::MySome(42) {
        MyOption::MySome { x: 42 } => (),
        _ => (),
    }
}
```

We now emit E0769 "tuple variant `MyOption::MySome` written as struct variant"
instead of E0026 "variant `MyOption::MySome` does not have a field named `x`".
