/index.html.acl present, /index.html missing: requesting / returns /index.html.acl

[csarven]

Issue occurs in v5.0.0-beta.7-6-g217e8e3 .

If index.html is absent and index.html.acl is present, request to / returns the contents of /index.html.acl . Expected: return container

If /index.html.acl is also absent, returns container.

How to reproduce:
Fresh install. (Added public read policy on /.acl to simplify)

$ bin/solid start
$ mv data/index.html data/foo.html
$ curl -ikL https://localhost:8443/

Oh, OK. So, I suppose something went wrong with the #1067 fixing? Could you check, @megoth ?

[megoth]

Yes, this sounds like an unexpected outcome of the special handling root...

I'll take a look!

So after a bit of research it seems that the problem is in the resourceMapper that picks index.html.acl because it tries to find a file that matches with index. So nothing to do with #1067. I'll push a PR with a fix soon.
