tdf#137802 sw: fix crash of textbox anchored to page

This is a regression from commit
a7bd634371285dbdceaf775dc31b6b586c7ca02f
(tdf#137802 tdf#84691 sw: sync anchoring of
textbox with UNO), where synching didn't
remove the anchoring setting.

Steps for reproducing:

1. In an empty document add a new paragraph so that you have two.
2. Insert – Shape – Basic Shapes – Rectangle and place it to the
   center of page to have it anchored to the second empty paragraph.
3. Right click on the shape – Add Text Box
4. Right click on the shape – Position and Size
5. Set Anchor as To page
6. Delete the second paragraph that the shape was anchored
7. Click on the shape and press Delete
