this will fail on chromeos (there are no apps in the NTP with chromeos). You can
check for this scenario with templateData.shouldShowApps.

[Danh Nguyen, 2012/03/13 15:02:21]

Done.  I've also fixed similar instance in the test 'NTPHasThumbNails'.  Also
excluded the test 'NTPHasLoginNameWhenSignedIn', which is irrelevant for Chrome
OS.

Done.
