fix go-to date

setting the week-day here was once necessary when Etar was still using `android.text.format.Time`, where the days where 0-indexed (`java.util.Calendar`s days are 1-indexed).

doing this with `com.android.calendarcommon2.Time` is wrong, and will result in sundays being one week ahead.

additionally, setting the `DAY_OF_WEEK` without updating the `WEEK_OF_MONTH` will result in the old value of `WEEK_OF_MONTH` being used, as `Calendar` expects these to be set in combination when doing the computation: https://github.com/openjdk-mirror/jdk7u-jdk/blob/f4d80957e89a19a29bb9f9807d2a28351ed7f7df/src/share/classes/java/util/Calendar.java#L1729-L1740
