Re-enable index file store at the end of the SimpleCache.initialize()

Browse Source 
In the case converting cache files from an earlier version of
SimpleCache, there is no previous version of the index file. If the app
doesn't call any SimpleCache methods which would make the index file
stored before it exists whole data gets lost.
