Subject: [PATCH] CACHE: Create timestamp if missing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In some cases, object is stored in cache but the corresponding
record in timestamp cache is missing (for example when timestamp
cache file is deleted). The timestamp is never created in such
case.

With this patch we create new timestamp object if update doesn't
work for this particular reason (missing object).
