What steps will reproduce the problem?
1. Install an extension in chrome that doesn't use the settings_override API yet
2. Change that extension to use the settings_override API to change the default search 
3. Update the extension in chrome to the new version using the API

What is the expected result?
The extension updates without any notifications and the extension stays enabled. On the first search the user is asked if that is the search result they expected and are given the option to easily revert their default search.

What happens instead of that?
The extension is disabled with a notification the same way as if a new permission was requested. 

Please provide any additional information below. Attach a screenshot if
possible.

Using the settings_override API is handled as if a new permission is requested, which is called {"searchProvider":"www.test.com"} when you list your permissions afterwards. But requesting this as an optional_permission does not work. This means there is no way to introduce this API to an existing extension without it being disabled automatically on update. As there is already a safeguard for changing the default search by showing the user a popup on the first search I'm unsure that this is intended behavior, especially as this seems to not happen for the page_override API, which shows a similar popup.

This issues can repoduced on OSX and Windows for at least Chrome Version 58, 59 and 60.

I attached screenshots for the relevant notifications (sorry, they are mostly in German).
