Don't special-case LiskDAO->load(0)

Browse source 
Summary:
Lisk currently behaves in two different ways if you call it like `load("cow")` (throws) versus `load(99999999)` (returns null), where neither ID exists.

This was intended to catch programming errors as distinct from missing data, but in practice the former is very rare and you have to handle the latter in most cases anyway. The case where you pass "0" is particularly confusing. See D2971 for an example.

On the balance, I think this ends up being far more confusing than helpful. Instead, just return NULL if we're sure there's no such object.

Test Plan: Reasoned about program behavior.
