introduce an error in Frame.isSpare

correct implementation should be
	return !isStrike() && frameTotal() == BONUS_WORTHY_SCORE;
Add an error in FrameTest.aStrikeIsNotASpare

to compensate the one introduce in Frame.isSpare
The correct code should use an AssertFalse instead on an AssertTrue. Copy/paste is bad :p
Forget spare stuff in LastFrame. oupsss.

correct implem should be
	return isStrike() && allRollsHaveBeenMade() ||
                isSpare() && allRollsHaveBeenMade() ||
                !isStrike() && !isSpare() && twoRollsHaveBeenMade();
Remove test about spare in LastFrameTest
correct indentation
correct indentation in test
remove code
