[Tracking Requested - why for this release]: Permafailing test on the next merge day. https://treeherder.mozilla.org/logviewer.html#?job_id=150916313&repo=try TEST-UNEXPECTED-FAIL | browser/base/content/test/performance/browser_startup_flicker.js | Uncaught exception - at chrome://mochitests/content/browser/browser/base/content/test/performance/browser_startup_flicker.js:12 - TypeError: Cc['@mozilla.org/test/startuprecorder;1'] is undefined

The early/first merge will be Jan. 11th. Tracking so we can make sure to check back in early January.

This got IRC r+ from Florian already. Since startuprecorder.js is only shipped on debug and trunk builds, only attempt to run the test there. Green on Try.
