fix git reconciler error: worktree contains unstaged changes

[acornett21]

Motivation

The git reconciler has a pretty noisy error message for the below, which makes it hard to troubleshoot other errors that can occur. This also happens after the git reconciler has successfully reconciled, so it makes the logs/status even more confusing. This seems to be happening if someone is using a tag/commit other then main, which is the recommended approach.

Changes

• Check what the git status is.
• Reset the working tree and discard local changes (changes here means something other then main it seems).
