Autocomplete doesn't work as expected when working with Objects if the Object contains key named `value`

[wildbsiu]

Describe the bug

Autocomplete doesn't behave as expected when working with objects and object has a key called value. When selecting an item from Autocomplete suggestion, expected selected item is supposed to be an object containing all the keys in the object. But selected item contains only value key.

However, if I simply rename value key to something else, say code, then behavior is as expected. Selected item in this contains all keys from the object.

Based on the example for Autocomplete when working with objects - https://primeng.org/autocomplete#objects, I have forked the StackBlitz example to showcase the issue at: https://stackblitz.com/edit/7pl9oavs-6kg2ha5d

Steps to reproduce the behavior

1. Head to the StackBlitz example and run the same.
2. Select any item from the autocomplete.
3. Selected item json shows only the value key. e.g if you select United States, the selected item is shown as US instead of expected {name: 'United States', value: 'US'}
4. Now, simply go the file countryservice.ts and rename key value to something else like code. Save and run.
5. Selected item now shows full object.

Expected behavior

Selected item should contain all object keys

I have the same issue with data coming from an API. However, I found a workaround. If you bind the optionValue property of the p-autoComplete to a function (e.g. [optionValue]="optionSelf"), then you can define this function in your component:

optionSelf = (item: any) => item;

@ChristianOssVos Thanks for the solution. It worked perfectly.
