Problem/Motivation
In #3112790: System and User modules are installed twice we tried to remove the user module installation from install_base_system() and let it be handled with the rest of the modules. This had two impacts:
- Installation from configuration for DrupalCI (couldn't reproduce this fail locally)
- Changing the language that user 0 and user 1 are created in - this is probably a bug in HEAD but changing this behaviour shouldn't happen here.
Proposed resolution
Try remove it and fix the tests.
