Correct day when adding/subtracting month/year

• If a month contains 31 days, and you run +1month, javascript rounds up to the 1st of next month
• This is not desired behaviour, as we really want to skip one month (both moment and dayjs agrees here)
• simple-date-parse now adjusts day, to make sure 31 becomes 30 if needed to stay within boundaries

Revert setMilliseconds(0)

• Actually made it harder to compare dates

setMilliseconds(0) for easier comparison
