store.cache.dispatch treat falsy values as undefined

[VitorLuizC]

The argsToString function ignore falsy values.

vuex-cache/src/index.js

Lines 10 to 12 in 637815b

	if (args[1]) {
	type = `${type}:${toString(args[1])}`
	}

We shouldn't ignore any value, even undefined should be used to generate cache's key.

This can be checked by running the code below.

import Vue from 'vue';
import Vuex, { Store } from 'vuex';
import cache from 'vuex-cache';

Vue.use(Vuex);

const store = new Store({
  plugins: [
    cache({})
  ],
  actions: {
    hi(_, payload) {
      console.log('Hi', payload);
    }
  }
});

store.cache.dispatch('hi', undefined); // It shows 'Hi undefined'

store.cache.dispatch('hi', null); // It don't show anything

store.cache.dispatch('hi', 0); // It don't show anything

store.cache.dispatch('hi', ''); // It don't show anything

store.cache.dispatch('hi', NaN); // It don't show anything

store.cache.dispatch('hi', false); // It don't show anything
