fix: empty trailing reference discarded all citation training data

When the reference segmenter ended the section with a bare label (e.g. a
number split off the last DOI) and no reference text, getExtractionResult
still emitted a result with an empty text. CitationParser.trainingExtraction
then returned null for the whole batch, so createTraining silently skipped
training.references.tei.xml and training.references.authors.tei.xml.

- drop a trailing chunk without reference text, as already done for the
  other references
- skip blank inputs in trainingExtraction instead of aborting the batch
