Intl Era Monthcode: Complete Hebrew leap month addition tests

Browse Source 
This adds tests for overflow constrain/reject with years, expands the
coverage with months to test edge cases using 12, 13, 24, and 25 months,
and cleans up a bit.

I started to add weeks and days tests for this in the previous PR, but
on reflection I don't think those are that useful.
