1. snap foo is released rev 2 for beta channel, if there are rev 1 and 2.
2. press "unpublish" button in the store UI, snap foo would be unpublish.
3. If we want to publish foo again, we can find release button for foo rev 1 or 2.
4. press release for rev 2, there is a dialog to ask which channels for release. If we just selected beta. The snap state is still "Ready to publish".

 >>> The behavior would confuse users.

4*. if we select other new channels, the snap state would be change to "Published"

 >>> This is what we expected.
