Component: MultiSelect - Filter not working for grouped items

[jpgoelz]

Describe the bug

When using grouped select items for the MultiSelect component, filtering no longer works, even for SelectItems that have a label property. It is now necessary to explicitly specify optionLabel="label", which is a regression.
The same is true for optionValue="value". The whole select item is being emitted, if this is not provided.

The problem can be seen in the demo for grouped items on the PrimeNG website: https://www.primefaces.org/primeng-v16/multiselect#group.

PrimeNG versions

16.9.1, 17.0.0

Build / Runtime

Angular CLI App

Language

TypeScript

Steps to reproduce the behavior

1. Add a MultiSelect component with SelectItemGroup that use SelectItem[].
2. Use the filter to filter for items. Nothing will be found.
3. Add optionLabel="label" and optionValue="value" and try again. Elements will be found.

Expected behavior

When using default SelectItems, label and value should not need to be specified as an optionLabel resp. an optionValue.

This problem persists in v17.

I updated the issue, because it also applies to optionValue="value".
