fix(i18n): make sure namespace params from useTranslation hooks are not passed with empty value

[alexandre-combemorel]

When using the hook useTranslation, previously the first param was an array of string, but it was allowed to be undefined or empty array.

Before:
useTranslation(undefined, loadTranslationFunc)
useTranslation([], loadTranslationFunc)
After:
useTranslation(['myNamespace'], loadTranslationFunc)
useTranslation(['myNamespace', ...], loadTranslationFunc)

now it has to be passed with at least one element in the array.
