feat(autoform): add default value on array, set value 0 to show on form input

[tyghaykal]

Refer to my issue on here #62, I've tried on my own project and it works. I've add the test too.

Changelog:

• Add capability on array with default value (array.tsx)
• Value 0 to be shown on input form
• Add tests set default array and value 0 to be shown.
