Original change's description:
> [Android][Gardener] Fixing ChromeTabbedActivityTest
>
> ChromeTabbedActivityTest#testBackShouldCloseTab_Collaboration was
> failing because of a NullPointerException.
>
> When tabCreator creates a new tab Chrome tries to show an IPH message
> related to version updates. The VersionUpdateIphHandler is responsible
> for this and needs to get the VersioningMessageController from the
> TabGroupSyncService.
>
> Mock TabGroupSyncService is used in the test, but it doesn't specify
> what should happen when getVersioningMessageController() is called. By
> default, Mockito returns null. This null controller is then passed
> along, leading to the NullPointerException when one of its methods is
> invoked.
>
> Mocking the VersioningMessageController should fix the test.
