server: fix url parsing in info

Browse Source 
When we are activated by systemd the code assumed that we had a valid
URL which was not the case so it failed to parse the URL which causes
the info call to fail all the time.
This fixes two problems first add the schema to the systemd activated
listener URL so it can be parsed correctly but second simply do not
parse it as url as all we care about in the info call is if it is unix
and the file path exists.

Fixes #24152
