Description
### Element UI version
2.15.3
### OS/Browsers version
win10,chrome
### Vue version
2.5.21
### Reproduction Link
https://jsfiddle.net/9vnj8w4e/
### Steps to reproduce
当我多选了多个文件之后,我发现选错了一个,我想删除掉一个,是没办法实现的,因为触发before-upload事件的同时,也会出发on-remove或者before-remove,我如果在这两个钩子函数做删除(before-upload(file, fileList){ this.fileList = fileList }),那么我选择上传的文件就会少一个
### What is Expected?
当我多选了多个文件之后,我发现选错了一个,我想删除掉一个,是没办法实现的,在on-remove或者before-remove做删除(before-upload(file, fileList){ this.fileList = fileList }),文件列表正常删除掉一个。
