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

[Patrick Zhang]

Hi Team,

Please help to review test modification for HijrahDate and HijrahChronology.

Description:
1. Enhance one data provider and make it support new added test for 
isLeapYear() and lengthOfYear()
2. HijrahDate.from(isoDate) should return corresponding HijrahDate 
instance correctly. It should work same as HijrahChronology 
.INSTANCE.date(isoDate)
