DaySelectedBackgroundColor is not respected when selecting days between years

[andrewindayang]

When selecting days across or within month (e.g. from 1 January to 31 January, or 1 January to 1 February), the selected days respects the DaySelectedBackgroundColor that I specified.

However, when selecting days across years (e.g. from 30 Dec 2015 to 10 January 2016), the selected days does not respect my DaySelectedBackgroundColor. The font is changes color but the background doesnt do that.

@andrewindayang how could do put the rectangle black on the range dates?
