Invalidate the AutoText Dialog after selection

Changes:
- added invalidate call after entry selection and expand

Behaviour before patch (Linux):
1. Open Writer
2. Open AutoText Dialog: Tools > AutoText
3. Expand/select entry

Insert button is still disabled / entry is not expanded.
To force repaint you had to use mouse scroll.
