Revert of Add a whole-app-list unit test. (https://codereview.chromium.org/210083009/)

This patch broke 'sizes' by adding a static initializer. Seehttp://build.chromium.org/p/chromium/builders/Linux/builds/48686/steps/sizes/logs/stdio for the detailed dump.

Original issue's description:
> Add a whole-app-list unit test.
> 
> This establishes a test harness for doing tests that touch on multiple
> parts of the app launcher UI, or that need coverage for the various app
> launcher configurations: Ash or Desktop; regular or experimental
> "landscape" mode.
> 
> It currently just tests displaying and closing the app launcher in its
> default state with a flat (no folders), 2- or 3-page model.
