OptionsAction Initialization crash if list empty: Need to handle when empty list is passed

[sbvis]

Example from the cluster differential expression plugin(https://github.com/ManiVaultStudio/ClusterDifferentialExpressionPlugin/blob/41ad57c3f9236a7de6fce70d107b884a89b5b8c2/src/LoadedDatasetsAction.cpp#L115):

    if (!clusterNames.isEmpty()) //need to add this check in the LoadedDatasetsAction.cpp
    {
        QStringList firstItemSelectedList;
        firstItemSelectedList.append(clusterNames.first());
        clusterOptionsAction.initialize(clusterNames, firstItemSelectedList);
    }
