There is no workaround for the incorrect registration of multipoint views as type Point. However, the multipoint geoprocessing tool issue can be resolved by clearing the workspace cache using Python after running the arcpy register. For example: arcpy.env.workspace = "<a href="file:C:/Users/rex8699/AppData/Roaming/ESRI/Desktop10.5/ArcCatalog/rex_SDE_ORACLE.sde" target="_blank">C:\Users\rex8699\AppData\Roaming\ESRI\Desktop10.5\ArcCatalog\rex_SDE_ORACLE.sde</a>"arcpy.ClearWorkspaceCache_management()
