Admin page translation issue

[Loki3000]

Steps to reproduce

1. open /index.php/settings/admin url
2. look at left menu

Expected behaviour

Expected that left menu is localized

Actual behaviour

Localized only one item of left menu

Server configuration

Operating system:
ubuntu 16.4
Web server:
Apache2
Database:
mysql 5.7.16
PHP version:
PHP 7.0.12
Nextcloud version: (see Nextcloud admin page)
10.0.1 (stable)
Updated from an older Nextcloud/ownCloud or fresh install:
Updated form ownCloud

I've a little dig in this problem and get follow:
in lib/private/Settings/Manager.php:332

0 => [new Section('server', $this->l->t('Server settings'), 0)],

$this->l contains strings from core/l10n/*.json file
but required string 'Server settings' (and followed strings) contains in file lib/l10n/*.json

Could you have a look into that 😁 @MorrisJobke ... On Transifex it seems to be translated 🤔

[Loki3000]

Yes strings translated, but placed in other dir:
file loaded into $this->l object
core/l10n/*.json

file contains required strings
lib/l10n/*.json

@Loki3000 you may want to fix this directly over an PR? 😁

I don't know right solution. Maybe translate strings placed in wrong place, and also maybe that to Manager.php was sent wrong object as a parameter.
Someone who knows the code should confirm that it is not the second case.
