[ASTERIXDB-2250] Clean up files after failed flush/merge

- user model changes: no
- storage format changes: no
- interface changes: no

Details:
- Currently we didn't clean up component files if the flush/merge
operation fails. As a result, when a failure happens, the subsequent
retries must fail as well because the files already exist.
- This patch cleans up component files when there is exception thrown
during flush/merge operation
- Added a test case on failed merge
