Return singleton from getAll if header doesn't exist. (#9836)
Motivation:

It is more efficient to avoid allocating objects when we don't need to.

Modification:

Don't allocate a `LinkedList` for returning an empty list of header values when the header doesn't exist at all.

Result:

Less allocations
