kio copy isnt paused when clicking on the pause button in file copy plasma dialog.

if you start a file copy (lets say a .iso file from folder A to folder B) and click on the pause button in the plasma file copy dialog, iotop shows that the associated kio-file copy still continues to copy the file instead of pausing and waiting for the "play/resume" action. the correct behaviour would be to stop the disk i/o and wait for the resume to occur.

Reproducible: Always

Steps to Reproduce:
1 - watch disk I/O via iotop 
2 - start a file copy via dolphin (like a .iso file)
3 - click on the pause button
4 - iotop (and HD led) shows that the associated kio slave still keeps copying the file, instead of waiting for the resume
5 - click on the resume button, the progression bar "jumps" to the point where the kio slave kept copying


Expected Results:  
when clicking on the pause button, the copy should STOP and WAIT for proper resume action. instead it still keeps copying the file which kinda defeats the purpose.
