ACL interface becomes blank

[danielmai]

Steps to reproduce via ?latest:

1. Connect Ratel to Dgraph.
2. Log in as groot. Default credentials are username groot and password password.
3. Click on ACL tab.
4. Click on "groot" row to show user info on the right pane.
5. Click on "Group" header row on the right pane.
6. The entire Ratel UI disappears, and the window is blank.

This error shows up in the console:
