Dead repos still show up on dashboard

[Brawrdon]

Describe the bug

I'm not sure if I should've made this an issue or discussion but...

I noticed on my dashboard bdougie/open-sauced was still taking up a spot after its transfer.

To Reproduce

1. Add a repo
2. Wait for that repo to be deleted, renamed or transferred
3. Watch as the old link sits there

Expected behavior

I'm not sure if it's possible, but it would be cool to see if there's a way to detect if a repository no longer exists and or has been moved. The related issue in the open-sauced-goals repo could then be deleted, updated or a new issue could be made all together.

If it's not possible to detect exactly what's happened to a repo, we could just delete any issue that ends up resolving to a repo not found error if they were accessed from click an item on the dashboard.

I think we can address this in the goals template. I opened an issue there. Since we are caching the data now, we force updates to issues that are associated to dead repos.

open-sauced/goals-template#8

This is indeed fixed. We now clear out dead repos with the caching sync 3 times a week.
