Bug 32002: Make submit button yellow on administration > Did you mean?

This patch corrects the class on the "Did you mean?" page's save button
so that it is consistent with other primary submit buttons.

To test, apply the patch and go to Administration -> Did you mean?

The "Save configuration" button should be yellow.
