option go_package bug

[Rkiouak]

Given a foo.proto importing another bar.proto, if bar.proto uses a go_package option, the require of the bar ns in the foo ns will be output as [ :as ]

This is either related to our not ignoring go_package, or the CodeGenRequest including the go_package under a separate key that we don't ignore or handle properly.
