[bug] History pages have their JS broken because owControllerApiHost is undefined

How to replicate in devices:

• create a device (or have an existing one created), make sure it has a config
• make changes to the config once it's saved
• click on history and go to the previous revision (open its details)
• open the console, you should see a JS error now, the "edit" icon is also not loaded properly

How to replicate in templates:

• create a device (or have an existing one created), make sure it has a config
• make changes to the config once it's saved
• click on history and go to the previous revision (open its details)
• go to advanced mode, you should see that the icon for the button to go back to normal mode doesn't load

Something identical happens in VPN Server too.
