I added tests in order to try to verify the problem with having a "link farm" in the source registry.
I was unable to replicate the issue, which seems to have been a false alarm, but I would like to merge these additional tests.
@frideau would you have a quick look? I think there may be a better way to remove the temporary link-farm
subdirectory when the test is done.
If you could have a look, we can squash merge this and move on to some of other open issues.
