Do not refresh object store before fetching object.
Before this commit the object store for a file token was always refreshed by reading the file of the token every time an object of the token was fetched. Now the HSM may be configured not to refresh when fetching an object. But the refresh will still be done after an application gets a handle for an object. The reason for this change is that the CPU time consumed by the reading may not be negligible for some HW. It is only the objects store on file that are affected by this feature. If DB is used refreshing will always be done since the is then no difference in CPU usage.
