tdf#137532: do not reset attributes deleting selection

Regression from 6abed0ea006f3616e40faf2ae782cf64f8ac2914

While at it, extend unittest for tdf#79717 to test another
regression from the same commit I found while testing the patch:
type 'a', type bold 'b', select both characters, type 'c'
-> it should be bold
