Subject: [PATCH] [FIX] Language: 48669: Install plugins with cli/setup.php

`ilLanguage` uses the `NullLogger` when `ilLoggerFactory` or
`logging.factory` is not defined in `$DIC`, as in the setup objectives
that build their own `$DIC`.

The fake `ilLoggerFactory` in `ilPluginLanguageUpdatedObjective` drops the
dead `getRootLogger()` override. Its fake `ilObjUser` returns the language
via `getLanguage()`, as `ilObjUser` no longer has `$prefs`.
