Description of problem:
If the Copy Translations process is halted via the admin Process Manager, the progress indicator stops but the box is still in the active state.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Pre: reasonable large project with documents
1. Log into zanata as admin and open two tabs
2. Go to the project version implied above, and in the other tab go Menu -> Administration -> Process manager
3. In tab 1, start a copy translations process
4. In tab 2, Cancel that process when it shows in the list
The Copy Translations box in tab one loses the progress bar, but remains
The box should either disappear, or indicate the process has been cancelled and say "Ok" instead of "Cancel"
Also, bringing the Copy Translations window back up at this point should just have the Start button, not Cancel
VERIFIED with Zanata 3.5.0-SNAPSHOT (git-server-3.4.1-39-g2204aa2)
