Fix CompositeFileTransferJob speed calculation

Browse source 
The `QElapsedTimer` was never started. Clean it up somewhat and use a dedicated
250ms timer for reporting transferred bytes periodically (like KIO does it) and
1000ms for calculating speed so it's not as erratic.

Furthermore, report final numbers in `slotResult` rather than complicating
`slotProcessedAmount` for that.

Also, fix typo "send" -> "sent"
