tdf#148551: sw ui: set default format value for Insert Field dlg

My previous implementation was changing current format selection
only for field edit dialog. However it should be initialized also
for insert field dlg. It is not always first element. Instead of
older confusing approach right now there is a switch to set
defaults: it is less confusing IMO.
