TermIt

When I toggle button to show/hide terms from importing vocabularies, it acts strangely. On disabling imports some external terms are shown. On enabling imports some external terms even become hidden.

Way to reporduce the issue:

• open vocabulary Slovník Pražských stavebních předpisů 2016 - slovník
• Ctrl-F5
• expand node "Lokalita nebo část lokality"
• expand node "Lokalita"
• issue1: there is an imported node Nezastavitelna lokalita that should not be here (Nezastavitelna lokalita is part of MPP-3.4. and since we are in mode "Without imported", i would not expect it to appear in the tree)
• click button so "Include imported" appears
• expand node "Lokalita nebo část lokality"
• issue2: node Lokalita is not expandable although it has "+" sign next to it (thus Nezastavitelna lokalita is not accessible anymore)
• expand node "Nezastavitelna plocha"
• note: It partially works as there is a node "Nezastavitelná transformační plocha" from mpp-3.5-np.
