While there maybe some fancy line of code that automagically restores the list, I would be tempted to install via pkcon.
You could start with pkcon search name accounts, this will show all available account plugins, then you can install VK account plugin with pkcon install jolla-settings-accounts-extensions-vk or may be Onedrive with pkcon install jolla-settings-accounts-extensions-onedrive.
You can also use pkcon to filter installed accounts/apps, by simply adding the 'filter' option in your command; pkcon search name --filter installed accounts - this will spit out which accounts plugins you already have installed, making the list easier to read.
