Logstorage: Sync behavior bug fix

This commit fixes couple of unexpected behavior on Logstorage sync behavior.
- A log file is created only if necessary to avoid creating an empty log file.
- The cache is synced with the condition:
  1) When the ring buffer is not wrapped around, the cache is synced from
     last sync offset to current offset
  2) When the ring buffer is wrapped around for first time and current offset
     is smaller than last sync offset, the cache is synced from last sync
     offset to end sync offset, and then from beginning to current offset
  3) Otherwise, the cache is synced from offset where the log message starts
     to end sync offset, and then from beginning to current offset
