Fix directory suggestion widgets in import tab when setting properties on multiple files

When importing multiple files in the IMPORT tab in the Web UI, directory suggestion widgets fallback to displaying directory entry label to directory entry ID after clicking on the EDIT NEXT / EDIT PREVIOUS.

How to reproduce:

• log in the Web UI
• navigate to a folder
• click on the + icon to create a document and open tab IMPORT
• drag and drop 2 files, click on ADD PROPERTIES button and select type File
• select Accomodation application form in the Nature field
  
• click on button EDIT NEXT then on EDIT PREVIOUS to come back to the first file

Expected result: field Nature shows Accomodation application form.
Actual result: field Nature shows accomodationApplicationForm, which is the directory entry ID.

This happens with single and multiple directory suggestion widgets.
