fix: fetch version from API on init instead of using hardcoded value

The version was stuck at "1.0.0" because fetchVersion() was only called
when initialLoad was true, but loadFromCache() set initialLoad to false
before fetchData() ran. Now version is fetched unconditionally in the
global store's init().

Fixes #144
