Subject: [PATCH 1/2] Object.seal sometime gets undefined value

Hi,

I see strange option `sockets` parameter which can be undefined if user didn't define it in `Vue` options. If I understand as right it may be bug.

It can be related with this opened issue: https://github.com/nathantsoi/vue-native-websocket/issues/75

And the [Object.seal should get the object type](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/seal#Non-object_coercion). If it will be not object ES5 code will throw error. I didn't test it but i saw code and think that's should be patched.
