Fixed #13985
UiStateTracker can process ActionProgress events after an ActionCompletion event
has been fired. This has the effect of recreating the action object in the activeActions
Map because Map.computeIfAbsent() is being used to retrieve the action.
Therefore, a new method getActionStateIfPresent is created which will return
the action if it exists, otherwise return null, and actionProgress() uses this
method so as to not inadverntantly recreate actions after they have already
completed and been removed from the Map.
