E0004 non-exhaustive patterns suggestion has unqualified enum variant

[ehuss]

Given the following code:

enum Foo {
    Variant1,
    Variant2,
}

fn main() {
    match Foo::Variant2 {
        Foo::Variant1 => {}
    }
}

The current output is:

    Checking foo v0.1.0 (/Users/eric/Temp/foo)
error[E0004]: non-exhaustive patterns: `Variant2` not covered

error: could not compile `foo` due to previous error

The problem with the suggestion is that it suggests Variant2 without the Foo:: prefix. Ideally the suggestion should be:

9 +         Foo::Variant2 => todo!()

The current suggestion does not compile.
