sw XHTML export: fix handling of list labels

This is building on top of commit
119b6876c92e4cdae44583c4b1b1419d3533e3ee (sw XHTML export: properly
write <li>...</li> around multiple paragraphs, 2020-05-21), but the
use-case here is a numbering with list labels only.

The first problem was that the list label had its <li> suppressed, but
not its </li>.

The other problem is that <ul> can only have <li> child elements, so at
least fix the case where the list only has list labels, in which case
even <ul> and </ul> should be omitted.
