We are renaming buyback guarantee to buyback obligation

The words "buyback guarantee" with "guarantee" crossed out and replaced by handwritten "obligation"; shield icon before "buyback".

At the very beginning of Mintos, we considered several names for the commitment from the lending companies to buy back loans in case of a borrower default. Eventually, the term “buyback guarantee” was chosen as we considered it a widely used legal term, understandable to all involved parties.
