Ensure save screen has all option data

[johnwatkins0]

Summary

Fixes #4971

This fixes a bug @westonruter brought up on Slack where the save screen sometimes doesn't have all data. This was because one portion of the screen was using the updates object from the options state. updates only contains options updated in the current session. This came about during an intermediate stage of development, and later on most instances of updates needed to be changed to editedOptions, which contains the original fetched options with updates applied. I missed this one earlier.

E2E is failing for some reason:

  ● Done › renders transitional mode done screen
    TimeoutError: waiting for selector ".technical-background" failed: timeout 3000ms exceeded
      20 | 	await visitAdminPage( 'admin.php', 'page=amp-setup' );
      21 | 	await clickNextButton();
    > 22 | 	await page.waitForSelector( '.technical-background' );
         | 	           ^
      23 | }
      24 | 
      25 | export async function moveToTemplateModeScreen( { technical } ) {

But this is also failing in develop.
