Writers.OpenDocument: fix invalid text:p inside text:p from meta

The only element in meta for which data/templates/default.opendocument
allows block element content appears to be "abstract", which is already
filtered out of meta' at this point, so simply convert all blocks to
linebreak-separated inlines.

Fixes: #8256
