sw XHTML export: properly write <li>...</li> around multiple paragraphs

Writer just has a list of text nodes, but ODF and HTML can have multiple
paragraphs inside <li>, in case the non-first text nodes have their
RES_PARATR_LIST_ISCOUNTED set to false.

Improve b6f7a4908d1c3fc610440a1cbbbc1673a53da8b6 (sw XHTML export:
properly write <li>...</li> around paragraphs, 2018-04-11) to make the
decision around when to write </li> based on not only the current but
also the next text node. This way we omit </li> for non-first paragraphs
inside <li>, but keep writing it in other cases.
