Make sure cursorPositionChanged is emitted when cursor position changes
Make sure cursorPositionChanged is emitted when cursor position changes

When selecting the text and setting the cursor position, we need to
emit the cursorPositionChanged signal. This seems to be a copy-paste
error from refactoring QLineEdit, as the function call is there in the
original version of setSelection(). The effect was two test breakages
in tst_QDateTimeEdit, because the section and cursor position of the
QDateTimeEdit would be out of sync.
