Cannot add two different Operation Repos if they share the same Holder folder

For example, if I add the Vision repo of Nodes and then try to add the Spinnaker Node (which also has a holder folder 'Vision') then I cannot add it because the symlink throws an error.

I need to look further down the holder folder and create the symlink at the level of the actual Node.

Actually what happens is that Heron throws an error but the actual Node folder structure gets copied as a symlink. Still it is better if the holder folder becomes a proper folder and the symlinks are only the Node folders inside it.
