Wrong version extraction for some packages

[Glyphack]

What steps did you take and what happened:
[A clear and concise description of what the bug is.]
I ran linter on contour project And got this:

internal/featuretests/tlsprotocolversion_test.go:20:2: version "auth" not specified in alias "envoy_api_v2_auth" for import path "github/com/envoyproxy/gocontrolplane/envoy/api/v2/auth"
internal/featuretests/tlsprotocolversion_test.go:21:2: version "listener" not specified in alias "envoy_api_v2_listener" for import path "github/com/envoyproxy/gocontrolplane/envoy/api/v2/listener"

What did you expect to happen:
package is couting listener as version, but it's not it should be v2.
