improve SummaryPluginConfig

[FrankHossfeld]

Add a new constructor:

  public SummaryPluginConfig(boolean removeOnEmptyData) {
    this.removeOnEmptyData = removeOnEmptyData;
  }

This new constructor will save a few lines of code. Instead of writing:

    SummaryPlugin<AngebotPositionListCompositeComponent, AngebotSummaryModel> pluginSummary = new SummaryPlugin<>();
    SummaryPluginConfig config = new SummaryPluginConfig();
    config.setRemoveOnEmptyData(true);
    pluginSummary.setConfig(config);

you can use:

    SummaryPlugin<AngebotPositionListCompositeComponent, AngebotSummaryModel> pluginSummary = new SummaryPlugin<>();
    pluginSummary.setConfig(new SummaryPluginConfig(true));
