tdf#86814 RTF import: fix sometimes lost bold style

The problem was that commit 76c0d0ab
(RTF import: adapt getProperties() to createStyleProperties(),
2014-09-07) only made the character style sprms/attributes a flat list,
but not the paragraph style ones. Fixing that inconsistency avoids the
tokenizer adding unwanted default sprms, which cause the bold sprms go
away in the bugdoc.
