imMicroFocus query on QML TextInput returns the start of preedit instead of cursor position

Start writing as preedit to QML TextInput. Results in micro focus query returning start of the preedit text as position. End of it would be more appropriate and the best would be to also honor QinputMethodEvent::Cursor if such is present.

QML TextEdit returns the end.

Affects meego virtual keyboard which uses microfocus position for placing word correction suggestion popup.
