Fixing some bugs around the repo listing — radicle-desktop

Fix showing onboarding instructions when there’s at least one repo in total
Remove unneccessary repo list reload
- If there is at least one repo, we don’t need to reload the repo listing.
Always reload the correct repo listing
- Don’t default to all repos for the repo listing reload, try to reload the repo listing according to the activeTab props and else go with all.
