Adding array values and reinitialising the form causes added fields to disappear

[lsjroberts]

I haven't been able to establish the root cause of this issue and if it is related to initializeState() when using destroyOnUnmount: false as per #430, or if it is more caused by some potentially incorrect behaviour of addField().

Given I initialise my form with

fields: [ 'bar[].deeper' ],
initialValues: {
  bar: [
    { deeper: 'baz' }
  ]
}

When I run

bar.addField();

I get

{
  bar: [
    { deeper: { initial: 'baz', value: 'baz' } },
    { value: undefined }
  ]
}

When I then type in my new deeper field at index 1 I get

{
  bar: [
    { deeper: { initial: 'baz', value: 'baz' } },
    { value: undefined, deeper: { value: 'typed value' } }
  ]
}

Similarly when I run

bar.addField({
  deeper: 'qux'
});

I get

{
  bar: [
    { deeper: { initial: 'baz', value: 'baz' } },
    { value: { deeper: 'qux' } }
  ]
}

The result of this that when I reinitialise the form index 1 of bar is dropped and I only see the correctly formed data:

{
  bar: [
    { deeper: { initial: 'baz', value: 'baz' } }
  ]
}

Thanks again, let me know if you need any further detail.
