Moving subfields of array field mix their values

[Pedro Sanchez]

Describe the bug

When the input is still idle (I mean undefined) and you try to change its position it takes the value of other subfields. It messes things up.

Codesandbox

Steps to reproduce

1. Try to move the empty subfields dragging and dropping in other position
2. Now try to move subfields with non-empty values

Expected behavior

I expect it to keep its value.

I think this is a bug with our moveValue method. I'll investigate in a bit
