FIX Config settings returned to normal after publishing completes

When calling this function onAfterWrite of a DO, the site theme was used to render the CMS form. This fix corrects that by restoring all the config options that are changed

When setting the start and count values for the `RebuildStaticCacheTask` the limits are ignored because the $urls variable is never reused after it is defined.
Fix incorrect set call.
