If a unicode escape is missing the curly braces, the suggested fix is to add the curly braces, but the span for the fix was incorrect. It was not covering the
\u, but the suggested text includes the\u, causing the resulting fix to be"\u\u{1234}". This changes it so that the span includes the\u. An alternate fix would be to remove\ufrom the suggested fix, but I think the error message reads better if the entire escape is included.
