Fixes #1354
This PR should fix the problem. Fix is somewhat hacky but at least there will be no panics.
In short: having interface as a generic field isn't supported by
go/types
(assert failure). Instead of copyinggo/types
functions and fixing it it's simpler to recover from a panic and ignore this struct in a checker.
