Successful if a member performs a full backup when its backup data is not present in the
performBackupBaseline (for whatever reason). This also tests what happens when a member is
offline during the performBackupBaseline backup.

<p>
The test is regarded as successful when all of the missing members oplog files are backed up
during an performBackupIncremental backup. This means that the member performed a full backup
because its oplogs were missing in the performBackupBaseline.
