[threeten-dev] Please help to review new test cases for java.time.chrono package

[Patrick Zhang]

Hi Team,

Please help to review the tests added for java.time.chrono.MinguoDate, 
JapaneseDate and ThaiBuddhistDate.
As final effort to cover all missed api, the code is put in related 
Chronology test class then we can reuse something.

Test description based on MinguoChronology:
1. MinguoDate.from(isoDate) should return corresponding MinguoDate 
instance correctly. It should work same as 
MinguoChronology.INSTANCE.date(isoDate).
2. Check the difference of isEqual() and equals().
3. Move function of isLeapYear() into separate test. And length of 
February of leap year should be 29 since its definition for "leap year" 
is same with ISO chronology.
4. Fixed some format issue in test class.
