Admin CLI :: 401 not authorized when user password is empty

[wajda]

On the default ArangoDB setup (user root with no password) the following command

java -jar admin-0.7.5.jar db-init arangodb://root@172.22.0.2/test

gives this

Exception in thread "main" za.co.absa.spline.common.rest.HttpStatusException: ArangoDB response: HTTP/1.1 401 Unauthorized. {"error":true,"errorNum":11,"errorMessage":"not authorized to execute this request","code":401}
