tdf#129578 rtfimport: CJK char properties are not CS
This fixes a LO 6.4/6.3.0.1 regression caused by
commit
fd95fb975b754d71d3750e85431a4e596a40e659
which was focused on export, and not import.
The code originally didn't have any
mention of DBCH, so it used the default.
However, in the 6.4 change, it was wrongly tied together
with the Complex Script indicator.
So revert that part of the change.
Mark fixed the same problem in 7.1 for font size.
