Create a real blank analysis

[jerolomb]

Is your feature request related to a problem? Please describe. The creation of a blank analysis (model) is linked to a model in the Back office

Describe the solution you'd like Have the choice to create a blank analysis (no link to a back office model). Really blank, no risks, no assets, no threats, no vulnerabilities etc.

For that we just need the deliverable's template.

This dev will also solve the issue to create an analysis in a language when the Back office database is not fully translated in this language
