## Overview

Fail gracefully for branch protection settings for private repos
(non-Pro).
- Added `warnText` field to the "withSpinner" options
- `withSpinner` will now store its callback return value, and will show
`warnText` in case the value is `false`

Bonus: I changed all the `catch (err)` to `catch (error)` just for
consistency (git blame on me)

I'm honestly not so excited about this solution, but submitting it
anyway to hear your thoughts
