Parameterized MixerTest to run both with and without field trial. 

This runs the full suite of tests with the AppListMixer field trial set
to both "default" and "Blended", for full coverage of both code paths.

Also, MixerTest.Basic now has different expectations in the "Blended"
case, because the mixing behaviour has (deliberately) changed.
