FIX: fully rely on keyValueStore to prevent error (#12) 

* FIX: fully rely on keyValueStore to prevent error

The component was generating errors for some users due to direct access to `localStorage`:

```
TypeError: Cannot convert undefined or null to object
    at Function.keys (<anonymous>)
    at Object.expireOldValues (https://d3bpeqsaub0i6y.cloudfront.net/theme-javascripts/33bf35dc19b970a42f8c1e7d57d8cc72d6205bbd.js?__ws=meta.discourse.org:157:14)

```

This commits removes old unnecessary code using cookies and uses latest API from core `removeKeys`. Old discourse instances will just not evict old keys which is a minor annoyance.
