Bug 1558770 - Remove non-functional test. r=kats

The test is supposed to test that changing the preference layers.acceleration.disabled doesn't cause a crash, but this pref is only read on startup well before the test has a chance to run and switch the pref. It's not doing anything. Differential Revision: https://phabricator.services.mozilla.com/D34781 --HG-- extra : moz-landing-system : lando
