src/dict/dictionary: fix duplicates in search results

Fix duplicates appearing in search results. This happened because terms
were sorted by their surface length, when they should have been sorted
by deconjugation length. This is because deconjugations will be used to
search for terms, so duplicate deconjugations means duplicate search
results. This fixes the issue by sorting by decending conjugation
length, breaking ties by prioritizing the longest surface.
