fix(go): panic on callback: using *<interface> as <interface> #2797

The callback handling logic was incorrectly handling "pure" interface
parameters. The reflection piece would create a new argument value in
preparation for the callback, however for interfaces, it would leave the
pointer to the interface type (as returned by reflect.New) instead of
indirecting to the interface itself as appropriate.

Fixes #2793
