message "The selected language is not available before the language pack is installed" wrong if no language can be chosen
The message is shown to a user if the be-user record has been created and a language has been defined which is not yet available.
It looks very strange to the editor because he doesn't know which language has been chosen. Therefore it makes sense to show the language title
How to reproduce:
- Create an BE user and set a default language which doesn't exist yet in typo3conf/l10n
- Switch to the user and go to the user settings module
