Expiration date displays inconsistently

Easy reproduction:

1. create a new document, set its dc:expired
2. edit the document, the dc:expired value you chose won't display
3. cancel the edit window, edit the doc again - the chosen value might be displayed (might not), cancel/edit until it displays

Reproduced on 9.10 (nuxeo-web-ui-2.2.0)
Did not reproduce on 9.3 (nuxeo-web-ui-2.1.3)

Another reproduction case from client report:

1. login into the app as an Admin
2. select one of the assets and click add to Collection button
3. in the pop up type a new collection name to create it
4. go to your collection and select newly created collection
5. Click Edit and specify an expiration date. Save it
6. Navigate away from collection and then back to collections view
7. Click Edit on a selected collection
   Problem: the expiration date isn't shown.
   Workaround: open and close collection's edit panel multiple times.
