Illegal .. notation for constructor LogOutView. The constructor has no labeled field

Given this code:

```haskell
data LogOutView = LogOutView

instance View LogOutView where
html LogOutView { .. } = [hsx||]
```

GHC errors with:

```haskell
Illegal .. notation for constructor LogOutView. The constructor has no labeled field
```

A better error message would be:

```haskell
The 'data LogOutView' has no fields, so you cannot use 'LogOutView { .. }' here. Perhaps remove the '{ .. }' here, or add some fields to 'data LogOutView'?
```

Start by reproducing the provided LogOutView example with GHC and confirm the current diagnostic for record wildcards on a constructor with no fields. Trace the diagnostic path for this error, then update it to explain that the data type has no fields and suggest removing `{ .. }` or adding fields. Done when the example produces the proposed clearer message.
