Remove already exist assertion while renew ccr lease (#46009)

If a CCR lease is disappeared while we are renewing it, then we will issue asyncAddRetentionLease to add that lease. And if asyncAddRetentionLease takes longer than retentionLeaseRenewInterval, then we can issue another asyncAddRetentionLease request. One of asyncAddRetentionLease requests will fail with RetentionLeaseAlreadyExistsException, hence trip the assertion. Closes #45192
