myLibrary/myCourses: New tab conflict

[jsschf]

Steps to reproduce

1. In Enterprises, click "Add documents"
2. When the dialog opens, click on the name of a document. A new tab should open
3. In the new tab, click "Add to myLibrary"
4. Close the new tab, navigate to myDashboard
5. Trying to delete any courses from myLibrary causes two console errors

The problem is that the new information for the dashboard is not loaded in the old tab. It's not limited to Enterprises or the Dashboard. If two tabs are opened and the myLibrary or myCourses items are changed in one, trying to change them in the other will fail.

Looks like there is no error message shown to the user, either.

I think we want to show an error with a "Please try again" and reload the information from the shelf database.

Note this is most likely to happen in real use by taking the steps above, but simply opening a second tab in your browser is the easiest way to test.
