Apps still show "update" button when "update all" is pressed [$25]

[Danielle Foré]

We should probably make those into cancel buttons

Also, "Update All" is still active while already updating all.

Setting status back to Confirmed because there's no evidence that the assignee has made progress. Feel free to re-assign yourself.

I am working on this issue.

Changes made so far:
 1. All apps now start to update at the same time (and are queued), all buttons of apps that are being updated are in 'Cancel' state.
 2. The 'Update All' button is disabled until all apps in queue are updated or cancelled.

I am resolving some issues in my code but this is almost working right now.
