Gadget state does not get modified by `undefined`


Gadget does not take `undefined` arguments as a change to context.

This makes using of default state almost boiler-plate free. Allows to
easily avoid unnecessary changes by having `undefined` in default state.

For explicite zeroing the state attribute, one should use `null` value.
