"Visualization" tab not working for thesauri

[martinaPulieri]

Is it normal that the "Visualization" tab doesn't show the hierarchical view of a thesaurus?

This component has not worked, for a long time, but it does work sometimes so we did not remove as we don't have a replacement yet.
Moved to ontoportal-lirmm#700, to see if can be fixed as it do work in BioPortal but not in AgroPortal.

@martinaPulieri do you want me to hide that tab?

in de89e75, I hid the tab visualization in the UI until we fix it in a future release (follow up here: ontoportal-lirmm#700)
