Reviewed by Tim Horton.

After https://commits.webkit.org/271515@main TestWebKitAPI.AutocorrectionTests.FontAtCaretWhenUsingUICTFontTextStyle
was failing because it used a method that no longer existed. The test needed to be re-written to use the API that
now gives the font information.

I also removed a duplicate line from the previous patch, no need to set the default black color twice.
