Hide input field in autosuggest if one item allowed and value selected

[GaziYucel]

Describe the feature
An change in the AutoSuggest component used on Contributors screen.

Currently, if only one item is allowed, the input value field is shown after selecting an item. This 'breaks' the layout, see screenshots. It would be better to hide the input value field if only one item is allowed and there is a selected value.

To Reproduce
Steps to reproduce the behavior:

1. Go to Dashboard > Open any submission
2. Click on 'Contributors'
3. Click on 'Edit' for a contributor or 'Add contributor'
4. Fill a search field in the Affiliations part
5. Select an institution from the list.

What application are you using?
OJS, OMP or OPS version 3.5.0
