Update git submodules

* Update Wikibase from branch 'master'
  to 224b59f3e0a01a7a7f9e313ec61098c3d56bc53a
  - Merge "bridge: put targetValue into statement only on save"
  - bridge: put targetValue into statement only on save
    
    This moves the mutation of the statementState to only after successful
    persistence (and round trip) to the server, allowing us to attempt a
    retry in the future.
    Consequently, the originalStatement state became obsolete and could be
    removed.
    Detection of changed state (by user input) happens by comparison between
    targetValue and the contents of statementModule.
    applyStringDataValue would not need to be an actual store action (maybe
    it is even somewhat confusing) and it can move out when implementing the
    different patch strategies.
    
    One downside of state update after successful save only: As actions are
    not tracked in vue dev tools[0], this makes for poor visibility of what
    is going on - the "mutations" are performed only on a copy of the
    statements state before submitting the change, which is not visible in
    the otherwise very helpful browser extension.
    
    I'm unsure about the value of the applyStringDataValue integration tests
    as they don't integrate a lot.
