Description: Fix PHP 8.5 compatibility regarding array_first() in test suite
 Under PHP 8.5, array_first(array $array) is a strictly typed native function.
 The unit test Framework_Bootstrap::test_array_first asserted that non-array
 arguments (false, string) return null, which now throws TypeError.
 Drop the non-array assertions matching upstream commit 060fc956724.
