This PR fixes issue #1850 .

If you call store.hasModule() with an array where none of the modules or submodules are registered in the store, an error is thrown instead of returning false:

TypeError: Cannot read property 'hasChild' of undefined
        at ModuleCollection.isRegistered (/node_modules/vuex/dist/vuex.common.js:291:17)
        at Store.hasModule (/node_modules/vuex/dist/vuex.common.js:611:24)
