Upload speed has incorrect value when resuming a folder with chunks

[ghost]

When I resume a folder that is uploading chunks of 20Mo to upload a huge file, the estimation of the bitrate seems incorrect :

The value is very big (33 Mbps !) and descrease slowly in time... (from 47Mbps to 2Mpbs)

I think the computation takes the "total already uploaded data" / "current elaped time".... while it should be "the current uploaded data (current chunk)" / "current elapsed time", resulting in a lower final value for the bitrate

Owncloud client 1.7.0 nightly build 04/12/14. Owncloud Server 7.0.3.4

Steps to reproduce :

• synchronize a file > 100Mo
• pause the sync after the first chunk (20Mo)
• resume the sync and check directly the estimated bitrate
• the bitrate is very high, bigger than the real bitrate

I observed the same issue with Windows OwnCloud Client 1.80.
My ISP upload speed is 1Mbit/s.
The client reports a wrong speed. Sometime too much. Sometimes a lower speed then the actual upload speed.
