Store properties undefined on "first render"

For a reason that I do not know, my store is undefined on "first render".

In that capture of devtools console, I log a property of my store.
It is **first** `undefined` then HMR comes and then the property is `defined`.


```js
import { Component } from 'preact';
import { connect } from 'unistore/preact';

@connect(['toast'])
class Toast extends Component {
render ({toast}, {}) {
console.log(toast);
return (

export default Toast;
```

```js
// store/worker.js
import createStore from 'stockroom/worker';
import idbKeyVal from 'idb-keyval';
import Constants from '../constants';

const store = createStore({
user: {
userId: '',
email: '',
avatar: ''
},
toast: {
messages: [],
show: false
}
});

// globally available actions
store.registerActions(store => ({
toasting ({toast}, messages) {
return {
toast: {
messages,
show: true
}
};
}
}));
```

```js
// index.js
import createStore from 'stockroom';
import storeWorker from 'workerize-loader!./store/worker';
import { Provider, connect } from 'unistore/preact';
import devtools from 'unistore/devtools';

const production = process.env.NODE_ENV === 'production';
const store = production ? createStore(storeWorker()) : devtools(createStore(storeWorker()));

import './style/index.scss';
import App from './components/app';

export default () => (



);
```

I don't have that problem when I only use unistore without stockroom.
