Harmonize Bidirectional, Outgoing, in Incoming count / individual Queries

[BenjaminHofstetter]

This is currently wrong.

• an bidi query should fetch only individuals that are bidirectional based on owl:inverseProperty or schema:inverseProperty.
• for in and outgoing individuals we should subtract the bidirectional results. Because we show only the "not" bidi results.

And we should state what bidirectional really means -> "that it's based on the ontology inverseProperty" and that the ontology must be part of the triple store.
