[ServerScenarioSelection] Scenario names aren't updated if language changed

1. Launch EE in English.
2. Start a server.
3. Select a scenario category. Observe the scenario names' language.
4. Return to the main menu.
5. Open Options.
6. Change the language to French.

Expected behavior:

Scenario names are in French.

Observed behavior:

Scenario names are in English.

This occurs with any two languages that have translated scenario names, in any order.

ScenarioInfo does not appear to be reloaded after changing the language. Adding logging on ScenarioInfo initialization:

INFO: ServerScenarioSelectionScreen created
INFO: Scenario info loaded
INFO: ScenarioInfo name: Bataille simple (Basic Battle)
INFO: Scenario info loaded
INFO: ScenarioInfo name: Encerclés (Surrounded)
INFO: Scenario info loaded
...
INFO: Loading scenario list
INFO: Entry: Bataille simple
INFO: Entry: Encerclés
INFO: Entry: Vagues
INFO: Entry: Entrainement : Croiseur
...
(language changed in options menu from French to English)
...
INFO: ServerScenarioSelectionScreen created
(no "Scenario info loaded" lines)
INFO: Loading scenario list
INFO: Entry: Bataille simple
INFO: Entry: Encerclés
INFO: Entry: Vagues
INFO: Entry: Entrainement : Croiseur

Start at ServerScenarioSelectionScreen and the ScenarioInfo initialization or loading path, then compare what happens when returning after changing the language in the Options menu. Trace why the scenario list is reused without refreshed translated names. Done means scenario names reflect the newly selected language for the reported language-switch sequence, including switching between any translated languages.
