tdf#146728 lok: IME: preset formatting in the new paragraph

When we wrote something using Heading or Title style and
then moved to the next paragraph by pressing enter
we should get "Text Body" style in the new line.

Do not copy style. Use NOHINTEXPAND when inserting initially
so we can use EMPTYEXPAND later - at the end of composing -
and use correct styling.

followup for:
lok: IME: directly copy formatting for inserted text
