Renaming active ontology's IRI causes loss to the reference of its debugger instance
In an internal representation in [org.exquisite.protege.EditorKitHook] (https://git-ainf.aau.at/interactive-KB-debugging/debugger/blob/master/protege-plugin/src/main/java/org/exquisite/protege/EditorKitHook.java#L34) there exists a mapping from each ontology to it's corresponding debugger instance.
When the (pre-set) ontology IRI of an ontology will be renamed, the ontology debugger that is mapped to this (active) ontology cannot be looked up again. (mapped with the old pre-set IRI) in an internal representation (see Map<OWLOntology,Debugger> ontologyDebuggerMap
in [org.exquisite.protege.EditorKitHook] (https://git-ainf.aau.at/interactive-KB-debugging/debugger/blob/master/protege-plugin/src/main/java/org/exquisite/protege/EditorKitHook.java#L34)).
This results in a null pointer reference to the debugger instance with serious consequences to the usability of the tool (see screenshot below).
