[CrOS MultiDevice] Remove MessageTransferOperation kMultiDeviceApi references.

We are launching the new multi-device services and removing
the old functionality.  As part of the internal cleanup, we
are removing references to kMultiDeviceApi from
MessageTransferOperation - as the functionality it entails
will become the default action - and removing code that
relies on old methods.

Many of the tests that rely on fake classes that mimic old
functionality fail.  As a result, this CL disables those tests.
