Merge #1259: Bump bip39 dependency to v2.0

8694624 Bump `bip39` to v2.0 (Elias Rohrer)

Pull request description:

  We previously bumped the `bip39` version to 2.0 [in the 0.2X release branch](#875). Back then, bumping it in `master` was [assumed unnecessary](#875 (comment)). It seems this was erroneous, as the current `1.0.1` dependency is present since #793, which was merged before the bump in `release/0.27`.

  Here, we therefore bump the crate version in `master` after all.
