lexer: Fix span override for the first token in a string Previously due to peculiarities of `StringReader` construction something like `"a b c d".parse::<TokenStream>()` gave you one non-overridden span for `a` and then three correctly overridden spans for `b`, `c` and `d`. Now all the spans are overridden.
