Problem/Motivation

The SPARQL query breaks when a bundle filter is provided for a non existing bundle key.

Steps to reproduce

Tests provided in the PR.

Proposed resolution

Now, this is a bit tricky. One thought is to return an empty string of entities in case the bundle key filter is invalid. However, that would not be effective in negative conditions, or in nested conditions. Thus, I suggest that if an invalid bundle is provided, a random hashed URI will be used instead so that if the invalid bundle is required (=), then no entity will match the type, whereas if the bundle is mandatory to be different (!=), then all entities will have a different bundle. Same for 'IN', 'NOT IN' etc.
