sanjay 2372ac574f Fix file writing bug in CL 170738066. If the file already existed, we should have truncated it. This was not detected by leveldb tests since leveldb code avoids reusing same files, but there was code elsewhere that was directly using leveldb files and relying on this behavior. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=170769101		pirms 7 gadiem
