    tests: Unset CHARSET when testing locales to avoid it breaking tests
    
    The charset set in `CHARSET` overrides the charset after the `.` in any
    `LC_*` category (set via the environment or `setlocale()`). This will
    break many tests, but in particular it definitely breaks the
    `/GDateTime/format_mixed/` tests which are specifically checking
    different charsets being set for different `LC_*` categories.
