buffet: Fix crash when CommandInstance::SetResults() is invoked
The crash was a result of use-after-delete in
CloudCommandProxy::OnResultsChanged() where TypedValueToJson returned
std::unique_ptr while the JSON value was set to Dictionary by using
unique_ptr::get() on the temporary. Should have called release()
instead to transfer the ownership to the dictionary.
Added a unit test to buffet/device_registration_info_unittest.cc to
test this specific scenario.
