Publishing new data to a project that uses Collab will display a progress bar that never progresses, and just finishes when at 100%.

Reproduction Steps:
1. Open a project using Collab
2. Insert some large amount of data into the project, so the transfer will take a while
3. Publish the new data to Collab, watch the window say "Transfer Queued"
4. Observe that there willl never be any progress, it will simply go from "Queued" to completed

Expected Result:
Collab should display an updating progress of the in-progress upload, rather than simply going from queued to finished without any in-between step.

Reproducible in version 5.5.0b7 (bd91e53964bc).
