UI does not update after group delete

[mccalluc]

• Specific code commit: 4d61e10
• Version of the web browser and OS: safari and ff on mac
• Environment where the error occurred (Vagrant VM and site conf mode or AWS instance): Production test

Steps to reproduce

Please list all the actions and the input data used:

1. From the collaboration page, delete a group

Observed behavior

The list of groups does not update immediately: Instead the group remains on the list until the next interaction with the list.

Probably won't get to this issue, since the collaboration page will be removed at some point soon.
