Fix CalendarView to show the month title properly.

Step to reproduce:
Do this test on a Tablet (i.e. do in multi-pane layout)
1. Settings > Date & time > Uncheck the Automatic date & time checkbox.
2. Select 'Set date' and set the month to January and Done.
3. Re-select 'Set date' then you will find no month title just above the calendar.
