Fix test_formatToCharacterIterator_original

Two issues fixed:
1) The negative currency cases appear to have never been correct. Almost
certainly they would have had the sign bit as the first element in the
format.
2) The recent change in Android to support the Turkish currency format
broke the TR tests (previously obscured by 1). Bug 16727554 /
