Error when directive is updated

[alex3683]

Whenever the directive's update method is called I get this error:

13:59:38.227 vue.runtime.esm.js:1737 TypeError: Cannot read property 'context' of undefined
    at bind (vue-clickaway.common.js:22)
    at update (vue-clickaway.common.js:72)
    at callHook$1 (vue.runtime.esm.js:6289)
    at _update (vue.runtime.esm.js:6218)

    at VueComponent.patch [as __patch__] (vue.runtime.esm.js:6092)
    at VueComponent.Vue._update (vue.runtime.esm.js:2666)

The issue arose after updating from 2.1.0 to 2.2.2. So I had a look at relevant changes and found this new line https://github.com/simplesmiler/vue-clickaway/blob/master/dist/vue-clickaway.common.js#L22
The stack trace indicates that bind was called via update. When looking at update it's very clear, that the vnode argument is not passed on to bind, hence the error (https://github.com/simplesmiler/vue-clickaway/blob/master/dist/vue-clickaway.common.js#L70-L72)

@joshiste Ah, sorry, didn't look at the pull requests, if there already was a proposed fix.
