Adjusted testhelper for the hydraulic boundary location calculations on the grass cover erosion outwards failure mechanism: - Introduced function to retrieve all the hydraulic boundary calculations that have an output -- Applied where necessary WTI-1570
Adjusted the RingtoetsDataSynchronization service to clear the HBL outputs on GrassCoverErosionFailureMechanism HBL calculations - Cleaned up TestDataGenerator WTI-1570
