[Locale] fixed fallback locale

The `getFallbackLocale()` method in `Symfony\Component\Locale\Locale` did not return a fallback locale if the current locale (`Locale::getDefault()`) was a 5-char locale like de_CH.

`LocaleTest` failed when the locale was set to de_CH before running (see changes in LocaleTest).

(second attempt after messing up PR#5641)

[ConfigDumpReference] avoid notice for variable nodes

When a variable node has an array as default value, a notice occurs later on because of an "array to string conversion", which is turned to an exception in debug mode (mandatory in order to run this command).
