fdo#63428 writerfilter: fix paste of commented text ranges

There were multiple problems here:

- xFoo->createTextCursorByRange() got a text range argument,
  where the text range wasn't from the xFoo text
- it was assumed that all XText implements text::XParagraphCursor as
  well, but this is not true for e.g. comment text
- commented text ranges were pasted as normal comments (once again, the
  insert position wasn't passed around)
