### This helper will compare the version of the currently installed app and the version of the upstream package.
### $upgrade_type can have 2 different values
### - UPGRADE_APP if the upstream app version has changed
### - UPGRADE_PACKAGE if only the YunoHost package has changed
### ynh_check_app_version_changed will stop the upgrade if the app is up to date.
### UPGRADE_APP should be used to upgrade the core app only if there's an upgrade to do.
