  @param {sap.ui.core.Control} oElement - element for which we're looking for siblings
  @param {sap.ui.core.Control} oRelevantContainer - "parent" container of the oElement
  @param {string} sAggregationName - name of the aggregation of the action
  
  @return {Array.<sap.ui.core.Control>} - returns an array with found siblings elements
