Fix redirect issue

[alexander-veit]

This works for me locally. I am not sure why it worked before despite having homepageDemos": false. It should have always redirected to /app. Therefore, I am not 100% sure that this fix will work on higlass.io.

This will likely change custom docker builds. homepageDemos: false meant that the homepage is disabled for folks installing higlass on their own server.

The issue with the redirect is likely caused by changes to https://github.com/higlass/higlass-docker

Yeah, that makes sense. The only thing I found in higlass-docker concerning this is:
docker exec -it container-$STAMP-with-redis sed -i 's/HGAC_HOMEPAGE_DEMOS=false/HGAC_HOMEPAGE_DEMOS=true/' higlass-app/config.js in start_higlass_io.sh. Are we using this script?
Indeed, when I go into the docker container that is currently running on higlass.io, I see window.HGAC_HOMEPAGE_DEMOS=false; in higlass-app/config.js
Maybe we used this script before and now use only start_production.sh?
