Undefined behaviors

Undefined fields

Statebus hasn't decided whether undefined fields should be stripped out of objects, or preserved. As a consequence, it behaves inconsistently. Here's an example:

save({key: 'a'})
save({key: 'a', a: undefined})
bus.cache.a  // ==> {key: 'a'}

save({key: 'b', b: undefined})
bus.cache.b  // ==> {key: 'a', b: undefined}

We need to decide what to do with undefined fields, and sweep through the whole codebase to enforce it.

Zero-length keys

Statebus will often not recognize the '' key:

{key: '', ...}

Because '' evaluates to false, and quite a bit of code checks if an object has a key with obj.key.
