MySqlStatementParser解析带中划线的库名会丢失中划线后的信息

[KaimingWan]

写了个单元测试可复现问题：

    @Test
    public void parse() {
        String sql = "create database pudding-test";
        MySqlStatementParser parser = new MySqlStatementParser(sql, SQLParserFeature.IgnoreNameQuotes);
        SQLStatement sqlStatement = parser.parseStatement();
        Assert.assertEquals(sqlStatement.toString().toLowerCase(),sql);
    }
