Removed obsolete create extension for the general dune erosion input --> the corresponding meta entity is created by the failure mechanism create extensions alreadyWTI-1654
Adapt Create and Read Extensions: - Modified extension methods for the DuneLocationOutput --> Cleaned up files, implemented missing NULL check - Adjusted implementation of the Hydraulic Boundary Location Output create extensions --> replaced cast to byte with a convert according to our own guidelinesWTI-1654
Modified database design: - Introduced similar structure as the hydraulic boundary locations as in grass cover erosion outwards failure mechanismWTI-1654
Rewired Plugin: - Provide constructor arguments to instantiate DuneErosionFailureMechanism instances from the plugin: -- Rewired the Close View for data -- Cleaned up ViewInfo test fileWTI-1577
Rewired DuneErosionFailureMechanismView: - Introduced constructor arguments -- Cleaned up tests, removed tests that are related to the Data property --> Due to the constructor argument, it's not necessary to define behaviour for this property.WTI-1577
