Fix functional jobs

In Change-ID I8db34f31d35375dc9656d53ac7af644c28a3d3fe we updated
api-ref samples, but functional tests didn't run so we didn't detect
that those samples changes broke our functional tests.

This patch fixes the functional tests, updates remaining cases of
key_size, and enables functional tests for api-ref changes to prevent
this from happening again.
