Sample Flaky Test: ExtensionsActivityLogTest.TestActivityLogVisible

Original change's description:
> [Extensions] Add recent extension activities to the activity log page
> 
> Show recent extension activities by making a call to
> chrome.activityLogPrivate.getExtensionActivities whenever the user
> navigates to the activity log page. Currently, the activity type,
> api call, event count and page url (if there is one) are shown
> in descending order of event count.
> 
> Note: the activity log database can sometimes store more than one entry
> that has the same api call/event type. This CL currently does not
> group any duplicate activity entries.
