Refactor does not create raw identifier when necessary

[BenjaminBrienen]

Summary

Suggestion for "wildcard match will also match any future added variants" will unescape raw identifiers.

Reproducer

I tried this code:

enum Foo {
    A,
    B,
    C,
}
match Foo::A {
    Foo::A => {},
    r#type => {},
}

I expected to see this happen:

enum Foo {
    A,
    B,
    C,
}
match Foo::A {
    Foo::A => {},
    r#type @ Foo::B | r#type @ Foo::C => {},
}

Instead, this happened:

enum Foo {
    A,
    B,
    C,
}
match Foo::A {
    Foo::A => {},
    type @ Foo::B | type @ Foo::C => {},
}
