ILEX-102 Single term view - predicates graph view not connected to the data

[Aiga115]

Issue #ILEX-102
Problem: Single term view - predicates graph view not connected to the data
Solution:

1. Return name instead of default value from the getName function
2. Fix tooltip behaviour - it was not disappearing when scrolling
3. Make all accordions expanded by default
4. Fix UI of nodes - they are too long

Result:
