Panic with class highlighter

[Keats]

To reproduce:

1. Update sublime package subrepo to 207cf862
2. Run the following test:

    #[test]
    fn test_classed_html_generator_panics() {
        let current_code = "{\n    \"headers\": [\"Number\", \"Title\"],\n    \"records\": [\n        [\"1\", \"Gutenberg\"],\n        [\"2\", \"Printing\"]\n    ],\n}\n";
        let syntax_set = SyntaxSet::load_defaults_newlines();
        let syntax = syntax_set.find_syntax_by_token("json").unwrap();
        println!("{:?}", syntax);
        let mut html_generator = ClassedHTMLGenerator::new_with_class_style(&syntax, &syntax_set, ClassStyle::Spaced);
        for line in LinesWithEndings::from(current_code) {
            html_generator.parse_html_for_line_which_includes_newline(&line);
        }
        let html = html_generator.finalize();
        assert_eq!(html, "<span class=\"source r\">x <span class=\"keyword operator arithmetic r\">+</span> y\n</span>");
    }

It will panic with:

thread 'html::tests::test_classed_html_generator_panics' panicked at 'tried to restore cleared scopes, but none were cleared', src/parsing/scope.rs:450:29

Making src/parsing/scope.rs:450:29 a no-op (() instead of panicking) fixes the issue and it seems highlighted correctly (?).

Thanks for reporting. I believe my comment/diagnosis at #326 (comment) applies here.
