When a request is made to a URL that returns a 3xx response and the
:redirects option is set, the globally_stub_request/after_request
hooks are not paired properly.  Both hooks should receive the original
request and the redirect-following request.

This spec should probably be re-written to use the local webmock
server, but I couldn't figure out how to get it to conditionally
send a redirect response since it writes directly to the socket
and doesn't (as far as I can tell) have the request info available
in that scope...so there's not easy way to have it send a different
response for different requests :(.

See myronmarston/vcr#171 for the original VCR issue that caused
me to investigate this bug.

…ns a 3xx response and the :redirects option is set, the globally_stub_request/after_request

hooks are now fired for the original request and the redirect-following request.
