Beta add-on asking for resume after deleting first listed version

[ValentinaPC]

Steps to reproduce:

1. Submit a listed add-on and approve it (i.e. https://addons-dev.allizom.org/en-US/developers/addon/test-webext-secondbeta/edit)
2. Submit a second beta version for the submitted add-on
3. Delete the listed version
4. Go to "My Submissions" page and see your add-on status

Expected results:
The add-on has a status (maybe "Incomplete"?).

Actual results:
The add-on has 2 links: Resume and Delete together with the message "This add-on will be deleted automatically after a few days if the submission process is not completed."

Notes/Issues:

• Using the direct manage link for the submitted addon i.e. https://addons-dev.allizom.org/en-US/developers/addon/test-webext-secondbeta/edit the add-on status is "Incomplete".
• if the listed version is only disabled the add-on is listed as "Incomplete"
• Beside the "Listed version" text from manage page is displayed the beta version number - which is a bit confusing.
  Verified on FF50(Win 7). Issue is reproducing on AMO-dev and -stage.

Currently what happens in this scenario is the Addon stops being Approved, because it has no Approved listed versions, but it does have a listed version (the beta version) so it's status is Incomplete and shown as such.
The 'listed version' is shown as 1.1b as a beta version stops being treated as a beta version for latest version purposes because only Approved Addons can have a beta channel.

(It's all a bit muddled because beta versions are a type of listed version, rather than an explicit extra channel.)

Verified on AMO-dev FF51(Win 7) and obtained the following results:

• Add-on status: Incomplete
• Info message displayed in "Manage My Submissions" page
• adding an unlisted version will add an AMO label near the Beta version
• adding a listed version will turn add-on status to "normal"

@diox : If this is how it suppose to look, I'll mark this verified. Thanks!

Yep, that's it. We could do better in the versions page but I focused on making the message in the add-on list correct.
