[DO NOT MERGE] DatePickerDialog title initially incorrect if calendar view shown.

If the calendar view of the date picker dialog is shown we
do not use a formatted date as the dialog title since the
calendar view shows it, instead we show a static "Set date"
title. However, the initial state of the date picker dialog
on a tablet has a formatted date since the date picker widget
does not do a correct check whether the calendar view is shown
which returns a false negative resulting in a title with a
formatted date being added since the dialog thinks it has no
calendar view.
