sw_redlinehide: try harder to prevent SetRedlineFlags from messing things up

Rearrange the code added in 15f1555da8adfa81ea1d4b0d8b694164fddbb2ae
to set all layouts to non-hidden before moving redlines in the model.

tdf52550-1.doc contains lots of consecutive delete redlines that
when exported to ODF trigger asserts about wrong start nodes in
CheckParaRedlineMerge().
