The Homescreen background changes to system default after rotating the device, when other language than system default is selected.

Steps to reproduce

1. Go to Settings -> General.
2. From "Theme" change the theme to Dark.
3. From "Language" select any language other that the "System default".
4. Return to the homescreen.
5. Rotate the device to Landscape mode.
6. Observe that the theme changes.

Expected behavior

The transition is done smoothly, the Dark theme is still displayed.

Actual behavior

Rotating the device to Landscape mode when any language other than the "System default" is selected, causes the theme to incorrectly change from Dark to "Light" - like theme, with the white text color.
The incorrect theme will continue to be displayed on both Landscape and Portrait mode until the user will navigate to another page/menu.
