Module doesn't work with homepages that don't have an alias

Just to add some further steps to reproduce. You need uncheck "Include the current page as a segment in the breadcrumb" and "Use the real page title when available" which are turned on by default. Managed to reproduce it on a fresh simplytest.me install

Thanks for your contribution code looks plausible on a first look will takt a closer look and try when I get arraound to it.

Nice.

I ran into a small edge case where I have url.prefixes defined in language.negotiation.yml but I haven't yet enabled url detection and selection, so I added a check to make sure the prefix actually exists before the comparison takes place.
