Remove redundant triggerRefresh calls causing race condition

- handleCommitSuccess/Revert/Undo no longer call triggerRefresh
- gitStateChange\$ observable already triggers refresh for these operations
- Redundant calls caused 2 concurrent loadGitLog, causing CI test failures
- Local tests passed because both completed; CI failed because 2nd never completed

This ensures only 1 loadGitLog runs per git operation.
