Revert of mash: Add a couple of apptests for AcceleratorRegistrar. (patchset #2 id:20001 of https://codereview.chromium.org/1510713002/ )

Reason for revert:
AcceleratorRegistrarTest.AcceleratorsRemovedOnHandlerDestroy is flaky on both trybots and the main waterfall (see https://build.chromium.org/p/chromium.linux/builders/Linux%20Tests/builds/35418 for one random example where it failed).
