Fix default value for DateRangePickerDialog currentDate (#177448)
## Description

This PR fixes the default value for `DateRangePickerDialog.currentDate`.
Before this PR, the comment mentions that `currentDate` defaults to
`DateTime.now()` but this is not the case (the value is not
initialised).
After this PR, `currentDate` defaults to `calendarDelegate.now()`.
