Datepicker 'Next Month' button skipping months

[badampowell]

If the current selected day is greater than the number of months in the following month, clicking the next month button skips that month.

Example: Select January 29, then click next month. Expected that February would be displayed, but March is, instead.

Indeed, what a bug. It is quite easy to fix. @bekos should we fix it now or after the refactor? We just need to set the day also or something like that, I need to look better, but easy fix for sure.

Well, if when we move from dates we also set the day to day 1 seems to fix the problem, I wrote tests for it and I tested it and works perfectly. But since I am far asleep, I will recheck tomorrow and send an PR :)
