Element: el-select multiple with vuex

[jkehler]

ElementUI version

1.1.2

OS/Browers version

Chrome 54

Vue version

2.1.0

Steps to reproduce

I am unable to get VueX to work with a multiple el-select component. I've found numerous tickets that referenced #1632 and tried implementing it in my own code. This workaround works fine when multiple is not used. But when using multiple it does not work.

Seems working: https://jsfiddle.net/hq4scjto/15/
Please note that the initial value should be an array.

@Leopoldthecoder 示例中没有执行update函数，并没有触发input事件，而是通过数组直接push进了value中，严格模式下，报错

@Leopoldthecoder this is still an issue as @wilsonIs explains.
The input event will never be emitted when the multiple property is true:

This breaks compability with vuex. Please reopen this issue.

I'll try to fix this.
