Remove unused query_from_key_index field in audioDB object

Admittedly, I could have used it in the next commit (a modification of
sampling), but the plan is to produce a C API for sampling, whereupon
all need for this field will disappear, so preemptively zap it.

PREFIX mo: <http://purl.org/ontology/mo/>

SELECT ?signal
WHERE
{
        ?signal a mo:Signal.
}
