git: Do not log error if repository has no commits (#11163)

Thorsten Ball and Bennet created 2 years ago

This is a follow-up to #10685 which started to hide these errors instead
of displaying them to the user.

But the errors are still noisy and not actionable, so we hide them
instead.

Release Notes:

- Removed error message being logged when `git blame` is run in a
repository without commits.
