radicle/git/canonical: Actually use qualified refs — heartwood

Some tests actually do not use qualified patterns. The removed lines should not compile because the qualified_pattern! proc macro should validate the string literals at compile time, but it contains a bug and actually does not assert well-formedness of qualified refspec patterns. Rectify.

             pattern(qualified_pattern!("a/b/c/d/*")) < pattern(qualified_pattern!("*/x")),

                 < pattern(qualified_pattern!("refs/heads/*/x")),
             "example 1"
         );
         assert!(
