[Bug Report] Upload list transition has a bad behavior

Element UI version

2.4.8

OS/Browsers version

Mac OS Mojave, Chrome Version 69.0.3497.100

Vue version

2.5.17

Reproduction Link

Steps to reproduce

Just delete the file at the top of the list.

What is Expected?

When you delete then, you should just see the file stay in its place and disappear.

What is actually happening?

When you delete then, you will see that the file moves to the very bottom of the list and disappears.

This is due to the dynamic v-key value which is, in that case, based on the array index of the file. So on remove, all indexes changes.

How to fix this issue?

Here, instead of using index, please use file.name

file-list改为获取数据时，会出现很奇怪的动画。

手动上传执行submit()方法会触发文件删除方法，是bug还是正常的？
