* Add initial reproducibility tests * failing test for default_text_classifier (WIP) * track trouble to underlying tok2vec layer * add regression test for Issue 5551 * tests go green with https://github.com/explosion/thinc/pull/359 * update test * adding fixed seeds to HashEmbed layers, seems to fix the reproducility issue Co-authored-by: Matthew Honnibal <honnibal+gh@gmail.com>
