AutoComplete: grouped options are not selected with enter key

[erikhorlings]

Describe the bug

When selecting an option in an option group in p-utoComplete using the enter key, the selection is lost upon tabbing out of the field. This only occurs with Enter key and with forceSelection is true.

Environment

Angular 14.2.12, PrimeNg 14.2.2.

Reproducer

Steps to reproduce the behavior

Create a p-autoComplete with forceSelection is true and at least one grouped option. Navigate to that selection by using the arrow buttons and select it with the enter key. Press tab to move focus to another field. The selected value is now cleared.

Expected behavior

I expect the selected value to not be cleared.

The problem is in the method onInputChange of AutoComplete. I have a working implementation of that locally that proofs that it can made working by making this method deal with grouped options. I am willing to clean that implementation up and create a pull request for that, but that will take some time.

I have added a PR that solves the problem for me.
