[fix] Fix issue if classpath query returns more results (#519)

Previously, if this happened, we would not get any results to a query as two json results line by line are not valid json.

I am not 100% why this happens, one classpath seems to have paths starting with `bazel-out/k8-fastbuild/bin` and the other with `bazel-out/host/bin`, which I don't really understand, but this should be a good enough workaround
