fix(forms): Removes icon and title links from autocomplete results

Removes the links from all three search options:
 - groups
 - friends
 - users

As a side effect also makes it possible to override:
 - Title used in user/default view
 - Icon params for groups/default view

Fixes #5583
This allows us to pass the ```'href' => false``` parameter to the ```icon/default``` view.
