PR description

当先选择endTime， handlePanelChange 中的值为 [empty, xxx];
Before：

After：

• 修改 timepicker foudation 的 formatValue 逻辑，原逻辑未对 undefined 做处理，会导致 formatToString 抛出 error

TODO：
需确认的问题，当前 validateDates 的逻辑亦未对 array[0]为空，array[1] 有值的情况做判断，所以首次选择时，invalid 并不正确。第二次时才正确（即 input的 validateStatus更新，背景色为error 色）。
validateDates应该也需要做对应的变更。
