Use unsafe isCachedObjectValid with CheckObjValidityEnabled

If the ccdbManager.setLocalObjectValidityChecking() was set, then the method
ccdbManager.isCachedObjectValid(path, timestamp)
will use only cached object (if any) SOV and EOV to check its validity.
By defaults the timestamp of cache filling and Cache-Valid-Until timestamp
accounting for the possible overlap of objects validity
