Subject: [PATCH] core/test: ensure public key is invalid in test

When providing public key as a subslice, it still can be
decoded as a valid key, thus interop will not return an error
but rather push `false` on stack. This test is about providing
invalid key, so ensure this via setting invalid prefix.
