 I18N: Ensure `determine_locale()` does not potentially return an empty
 string.

 Call `get_locale()` as a last resort in case the sanitized locale is an
 empty string.

 Also swaps conditionals to cater for more typical use case and adds tests.

 Follow-up to [55862]

 Props Cybr, swissspidy.
 Fixes #58317.
