Bug found:
The code loads SPARQL queries from the knowledge graph that can have arguments (parameters)
The code that loads those arguments was commented out (disabled) - so the arguments dictionary was empty
But the code that builds tools from those queries still tried to access arguments[argument] for each query
Result: Crashed with KeyError because it tried to look up arguments that were never loaded

Fix:
Added a filter to only use arguments that actually exist in the arguments dict - if an argument isn't loaded, skip it instead of crashing.

@Dr0p42 ready for review

I think that we should instead have those started and running as docker container to keep it simple @jravenel

[jravenel]

good for me @Dr0p42, does it change the description above?
