Second part of reporting unsupported query types (#44)

Basically did the same thing as with aggregations. Tested receiving
every `Query DSL` query type possible, to see if we catch it. We seem
to. E.g. at the screens `shape` is a `Query DSL` unsupported query,
while `ip_range` is an aggregation - you can see both.

In the code I needed to only start returning if parsing went fine or not
for bool expressions, as they can contain subqueries with all other
`Query DSL` queries.
