Advance test-vectors commit in SVM conformance

[LucasSte]

Problem

The SVM conformance tests were using an old test-vectors commit.

Summary of Changes

I bumped the commit and made some adaptions in the test environment so that all fixtures could run correctly.

Lgmt, but just out of curiosity: why not symlink to protosol or add it to the build script somehow? Instead of reimplementing the protobufs here.

I left it like this just because there was no protocol repository when I created this test. I'll look into that improvement. Thanks for the hint.
