FIX: Sorting does not work when there are many items

[akashgp09]

Problem

Sorting isn't working as expected and undesirable results are observed when there are more than 8 items in the series.

Cause:

When an object is saved to the redux store in this order: { n3: { ... }, n2: { ... }, n1: { ... } } and when retrieved back, it is returned in a sorted form by default { n1 { ... }, n2: { ... }, n3: { ... } }

Additionally, position value is unnecessarily updated inside handleNumberAttributeChange event handler, which leads to inappropriate results in the case of manual ordering type.

Solution

• We need to sort the items in the frontend here, once the object is converted to an array.
• Removed attributePosition from handleNumberAttributeChange event handler.
