When you set that to nil you are explicitly asking tabulated-list to erase the header line. Just leave it as t instead.
As long as you don't call init-header, the header will be left as you set it.

Although your patch is technically unnecessary (what you want to do is already possible) it might be good to apply anyway.
The line of code that you remove in your patch might break stuff, but if it doesn't then it should be removed. But I'm not the right person to say that.
