Access rights issue for Admin user during clean install with Distribution Wizard

Here's what I did to reproduce the issue:

1. downloaded and unpacked xwiki-enterprise-jetty-hsqldb-5.4.2 zip
2. deleted the data folder
3. started XWiki and accessed the home page Main.WebHome
4. The Distribution Wizard was triggered immediately and I started the installation.
5. I was prompted to login
6. After logging in I got "You are not allowed to view this document or perform this action.". I reloaded the page and I got the Distribution Wizard (probably related to XWIKI-10071). The installation of "XWiki Enterprise - UI - Main wiki" was done. The progress log had a couple of:

7. I finished the wizard and I noticed that some translations were missing (the registration failed probably)

So there are two issues:

1. After logging in you need to reload the page (related to XWIKI-10071)
2. There are some access rights checks that fail for Admin user
3. Translation registration failed
