tdf#106953 RTF import: fix missing paragraph left margin

See commit 3915bf2dc877d5f1140798e24933db0f21386a4a (tdf#95376 DOCX
import: fix incorrectly indented tab stops, 2016-01-26) for the various
sources that can determine the paragraph indentation.

In this case the problem was that too aggressive RTF style deduplication
removed a direct indent, which then meant a fallback to the ind-from-num
value, not to the ind-from-parastyle one.
