Twenty Sixteen: Fixes quote block border not changing color.

The border was not changing color when it was changed. This brings that in. It is worth noting the original theme design did not have this but as noted in the ticket this has been in the quote block for about two years so matching the current block styling in this case makes sense.

Props umesh84, desrosj, sabernhardt.
Fixes #56565.
