Hitting ‘Enter’ in search doesn’t work in the link picker UI

When a users uses the link picker to add a document to a component then the search functionality doesn’t work when hitting 'Enter’. Instead the document that is selected will be added to the component.

How to reproduce:
Go green demo (https://cms.demo.onehippo.com/?1) - Channel manager - Component - Link picker - Fill in the search box - Hit ‘Enter'

This way:

• Search only works when users click the search icon
• It is possible that a user adds a (wrong) document by accident to the component
• It is impossible to change a search word/term without removing the current search terms (because the search icon automatically is replaced by a ‘remove’ (X) icon)
