Reverts #1220

It breaks the docker build and I don't have the time to investigate it right now.

I've no idea how to obtain the used Dockerfile, but I suspect that it is because

COPY .xml xep. *.css *.xsl *.js *.xsl Makefile /src/

which does not copy refs-LICENSE and in general it seems to be a bad idea to copy files from the repo over, as it is fragile (as demonstrated by this issue).
