Don't record class map objects outside of the requested scope

A code object will be created in the class map for org.springframework.web.filter.OncePerRequestFilter, despite that package not existing in the appmap.yml configuration.

Start by tracing how the supplied event is processed and how class-map objects are created, then inspect how the requested scope from appmap.yml is applied to the event's defined_class. Use the OncePerRequestFilter example as a regression case; done means classes outside the configured package are not recorded.
