0.1.43 does not return client and access-token with each response

Nobody has claimed this yet.

The latest version now wipes access-token and client for subsequent API requests:

https://github.com/lynndylanhurley/devise_token_auth/blob/00fa5f4507da806f66664787745086ce404d95b4/app/controllers/devise_token_auth/concerns/set_user_by_token.rb#L18

```ruby
# keep track of request duration
def set_request_start
@request_started_at = Time.zone.now
@used_auth_by_token = true

# initialize instance variables
@client_id = nil
@resource = nil
@token = nil
@is_batch_request = nil
end
```

The way we had our application set up was relying on those access tokens being returned as they were in previous releases.

Why was this change added? The commit only mentions passing tests: https://github.com/lynndylanhurley/devise_token_auth/commit/bdcd05e284e7fd0774005248a3239bfc889824c4

Start with app/controllers/devise_token_auth/concerns/set_user_by_token.rb at the referenced initialization and inspect commit bdcd05e284e7fd0774005248a3239bfc889824c4. Compare the response behavior with the previous release and review the tests that commit changed or relied on. Done means the intended client and access-token behavior is established and covered by regression tests.
