[autopatch] Autopatch to migrate to new permission system

[yunohost-bot]

This is an automatic PR

NB. : this is an automated attempt to migrate the app to the new permission system

You should not blindly trust the proposed changes. In particular, the auto-patch will not handle:

• situations which are more complex than "if is_public is true, allow visitors"
• situations where the app needs to be temporarily public (then possible private) during initial configuration
• apps that need to define extra permission for specific section of the app (such as admin interface)
• apps using non-standard syntax
• other specific use cases

PLEASE carefully review, test and amend the proposed changes if you find that the autopatch did not do a proper job.
