Default value not working for queries

[javierbrea]

Currently, when defining a default value for a Memory storage, it returns the expected value when reading the root object, but, when querying the source to get an specific property, it has as value the full object defined as default value too, not the value of the queried property:

import { Memory } from "xbyorange/mercury-memory";

const fooOrigin = new Memory({
  fooProperty: "foo",
  fooProperty2: "foo2"
});

console.log(fooOrigin.read.value); //=> {fooProperty:"foo", fooProperty2: "foo2"}
console.log(fooOrigin.query("fooProperty").read.value; //=> {fooProperty:"foo", fooProperty2: "foo2"}

It is desirable that, when querying an specific property, it returns the value of that property as default value, not the full object:

console.log(fooOrigin.query("fooProperty").read.value; //=> "foo"

In order to avoid breaking changes, this new behavior should be activated using a new option called "queriesDefaultValue". A warning will be traced if this option is not received until next major version, in which the option will be deprecated and the described behavior will be the default one.
