Same "next version" in multiple branches prevents from downloading the artifact

• You have two branches, master and another one.
• both of them have the same "next version"
• you checkout master
• you change to intermediate mode (it works in simple mode)
• you cannot get the artifact
• server logs are scarce:

  2017-03-30 16:36:32,498 WARN  [catalina-exec-988] [com.nuxeo.studio.servlet.StudioServlet] The version "0.0.1--wip--targuillere_72984b--master-SNAPSHOT" was not found for the project "coach-2017-04-nuxeo"
  

  Workaround: change the "next version" in master.

Update: not sure, maybe the real issue is the following:

• you create a project. It starts with a "next version", and generate everything it needs for that.
• you use the import for a branch, it updates the "next version" in the corresponding `application.xml` file, but this is done outside of the normal workflow, which would update metadata/artifacts for the new version.
• Thus when you update the "next version" through the regular way, you force an update, and artifact download recovers.
• application.xml change in the 'import' commit:

  <application>
  - <version>0.0.1</version>
  + <version>0.0.1-TEMP_FOR_TEMPLATE</version>
  

TODO
Check if this issue happens

• only after project copy (only happens to Nuxeo insiders and we have a workaround, lower priority)
• in other cases too (higher priority)
