Comment 2 for bug 1377371

Testing on "master" branch. Before Patch the "My groups" sidebar default setting was "0" and not blank, meaning all groups were showing. After Patch the default setting was "blank" AND when "0" was selected no groups were showing on the sidebar. Below are the steps I took:

Logged in as admin.
Go to Groups
Create Group called “Testing Group 1”
Save group
 Go to Settings
Go to Maximum number of groups to display
Delete “0” and leave it blank
Save settings
Refresh page
The number “0” should be shown
And My groups sidebar should be showing “Testing Group 1”
