fix: package list refresh based on logged-in user (#415)

* fix: package list refresh based on logged-in user

description:
In `pages/home/Home.tsx` now monitoring any change in a user log-in/out which will trigger a new `API.request` to get the _packages_ from the Verdaccio-server.  This is done by creating a `useEffect` on **isUserLoggedIn**.  Code has been transplanted from `App/App.tsx` including the use of the Loading component during the XHR.  The use of **packages** was removed from other components as no longer needed and tests updated.

Resolves issue #414
