fix: deepEqual validator

[VikalpP]

fixes #47

Problem:

Logically it was returning the comparison of the last key field.

Solution:

Comparision should end as soon as any of the key fields is not equal, and return false.

How to test?

const senderMenuItems = [ {text: 'Send', icon: 'trash'} ]
const receiverMenuItems = [ {text: 'Receiver', icon: 'trash'} ]
deepEqual(senderMenuItems, receiverMenuItems) // should return false
