So, the problem here was that both the seed and the value needed to be null in order to match this path.
When the bucket-able value is null we should bucket to 0, which is independent of the seed value.

Context doesn't have the missing attribute.

Seed was required to hit this code path.

When a rollout had a seed, and the context being evaluated was missing the attribute referenced by
bucketBy, then thenullatom would attempt to be used as a binary.When the attribute is
null, then the bucket value should always be0.This doesn't affect the experimentation logic related to presence of the context itself.
