In SEOChecker for v7, if I didn't choose a 404 page through SEOChecker, the default functionality from umbracoSettings.config would still be used.

In SEOChecker for v8, you get the default "page not found" page if a 404 page is not specified through SEOChecker.

STR:

1. Create a new project and install umbracocms through nuget
2. Build and start the solution and install umbraco using the starter kit
3. Go to umbracoSettings.config, and enter the GUID for the contact page as the 404 for the default language
4. Go to a non existing url
5. Notice that you are redirected to the contact page
6. Now install the SEOChecker package
7. Refresh the non existing url
8. Notice that you are now redirected to the default "page not found" page, instead of the contact page

Umbraco version: 8.0.2

SEOChecker version: 2.8
