Fix ExternalVibrationTest for parcelable serialization 

Use real instances of IBinder to create an IExternalVibrationController
before testing the writeToParcel/createFromParcel methods, as they rely
on the implementation of Parcel.writeStrongBinder that doesn't work on
mocks.

Also update the tests to assert on all fields from the restored
ExternalVibration, since the equals implementation only relies on the
client token.
