Can't create new deck (can't reached 10lv demonhunter)

This with workaround:

@Kerfluffle-11372

• (NEW) A bug where players can be locked out from creating or deleting decks when they previously were not.
  • If you find yourself in this game state, the current recommended workaround to unlock creating and deleting decks is to win 1 game against Demon Hunter in practice mode (Solo Adventures > Practice). It can also be done by winning 1 game against Demon Hunter in Arena, Tavern Brawl, Standard, Wild, Classic, or Casual.
