nuxeoctl rollback template feature leads to unpredictable results

Follow-up of NXCLI-67: installation of a buggy package can wreak havoc in nuxeo.conf

• install nuxeo-10.10 from ZIP

• nuxeoctl console

  and configure using the wizard:

  • default DB as H2
  • log dir as ./log
  • data dir as ./nxserver2/data
  • development mode to false
  • mail as port 25000
• once correctly booted shutdown Nuxeo
• edit nuxeo.conf and change
  • nuxeo.templates=mongodb
  • between line ### BEGIN and ### END where it is said not to edit, add line:
    nuxeo.mongodb.server=localhost:27001
    and save nuxeo.conf

• copy nuxeo.conf nuxeo.conf.mongo

• nuxeoctl mp-install /path./to/reproducer-package-1.0-SNAPSHOT.zip

  Installing reproducer-1.0.0-SNAPSHOT
  Template 'reproducer' not found with relative or absolute path (C:\CASES\SUP34436\NXP\nuxeo-server-10.10-tomcat\templates\reproducer). Check your nuxeo.templates parameter, and nuxeo.template.includes for included files.
  

• bash -c "diff nuxeo.conf nuxeo.conf.mongo"

  Notice that the specific line we manually added for mongo configuration has vanished (very very bad result => it might be better to throw an exception and not attempt to recover)
  Notice that the log dir and data dir line changed. Depending on history of wizard usage, some randomness in the values can be observed.

• nuxeoctl mp-uninstall reproducer

  does not cure the issue at all

All of this does not happen if no "rogue" template in the package (see NXCLI-67 for origin of the package)
