Tests failing due to probably import sorting issues about slicerdmri HOT 1 CLOSED

It turns out that the failures are triggered by the SampleData.downloadFromURL method at e.g.

The method ultimately calls ‎SampleDataLogic.downloadFromSource which covers a number of data type cases:
https://github.com/Slicer/Slicer/blob/17d23da3fddefd412aacc9f390c31f28379c0dba/Modules/Scripted/SampleData/SampleData.py#L682

It looks like the method is not working for the FiberBundleFile data type, and ultimately makes the process crash with the above error.

If one specifies a ModelFile data type at:

instead of a FiberBundleFile, the data is indeed loaded into 3D Slicer, but then it fails a few lines after that because the node at issue is not present in the scene, e.g.

  File "bld/slicerdmri/inner-build/lib/Slicer-5.5/qt-scripted-modules/TractographyDownsample.py", line 653, in test_TractographyDownsample1
    fiberBundleNode = slicer.util.getNode(pattern="fiber_ply_export_test")
  File "bld/slicer/Slicer-build/bin/Python/slicer/util.py", line 1517, in getNode
    raise MRMLNodeNotFoundException("could not find nodes in the scene by name or id '%s'" % (pattern if (isinstance(pattern, str)) else ""))
slicer.util.MRMLNodeNotFoundException: could not find nodes in the scene by name or id 'fiber_ply_export_test'

So this is not related to import sorting issues, and the failure is ultimately the same as the one reported in issue #207: closing this issue in favor of the latter and adding the failing test report in there.
