HAL serializer v2 fails if no actions are provided.

[inadarei]

Unless even empty actions is provided, output is an empty JSON

E.g. this works:

const representor = require('representor-serializer');
response.data = {};
response.data.someAttribute = someValue;
response.actions = [];

// Convert internal representation to HAL
response = representor(response, 'application/hal+json');

But when removing empty .actions code returns an empty object:

const representor = require('representor-serializer');
response.data = {};
response.data.someAttribute = someValue;

// Convert internal representation to HAL
response = representor(response, 'application/hal+json');

return {}

The two should produce identical output
