Prevent double slashes in full path.

During housekeeping 'Cache_S3' gets initialized with an empty 'dir' value.  This resulted in consecutive forward slashes in 'Cache_S3::get_full_path()', which prevented detection of directories and resulted in an empty list of rules.  'putBucketLifecycleConfiguration' with an empty list of rules causes a malformed XML error with AWS S3.
