[HUDI-1740] Fix insert-overwrite API archival (#2784)

Browse Source 
- fix problem of archiving replace commits
- Fix problem when getting empty replacecommit.requested
- Improved the logic of handling empty and non-empty requested/inflight commit files. Added unit tests to cover both empty and non-empty inflight files cases and cleaned up some unused test util methods
