有没有人遇到 appium1.3.4.1 版 sendkey 的时候删除原值再 send 时，文本框的最后结果为：原值 +send 值的情况
例如：日历插件输入框中日期为 2015-03-19，要输入 2015-03-20，先 clear 文本框，再 sendkey("2015-03-20")。其结果为 2015-03-192015-03-20。查看 appium 日志也显示发送的有问题。Sending plain text to element: 2015-03-192015-03-20
在 1.2.4 版无这样的情况，但是 1.2.4 版 sendkey 速度非常慢。
代码：

driver.SendKeyByElement(pageOrderQuery.text_order_depdate,“2015-03-20“);
