.all() recurrences are wrong if startDate is 31st day of month

[welmor]

In the current scenario:
startDate: '2018-12-31'
endDate: '2019-12-31'

moment().recur('2018-12-31', '2019-12-31').every(1, 'months').except('2018-12-31').all()

A monthly recurrence for the above should return 12 records, but returns 7 instead.

Between those dates (excluding the first occurrence), there are 7 months ending with 31st (january, march, may, july, august, october, december).

That's also true for .next(x) calls.

Same here, any solution?
