Method all_released_ids_for doesn't return a released_to_all response

[GLOFonseca]

Problem

When one checks all_released_ids_for a feature that was release_to_all, FeatureFlagger returns the ids from the accounts with the rollout before the release_to_all method. So we need a response informing that feature was released to all.

Example

account.release(:foo, :bar)
=>  true
Account.release_to_all(:foo, :bar)
=> true
Account.all_released_ids_for(:foo, :bar)
=> "1"

@GLOFonseca questions

• It's important to know what the ids previously released before the release to all?

• What's would be the best response in this scenario? I do not want to return a different response type for this method, like "released_to_all". I think that would be better to use the already implemented method called released_to_all? for this purpose. What do you think?
