message: fix(account-lib): change statics version back to ^6.0.0
  This version should match the version in modules/statics/package.json.
  The version is bumped as part of the release process, so overriding it
  in has no effect. The downside is that this causes
  yarn to generate an undesired entry in the yarn.lock.
