Steps to reproduce

1. Install Ibexa DXP
2. Try to create a new language and press enter

Result

The form save and we rediredt to edit page

Expected

After save the form we should be redirect to list language 

Note

This problem is repeated in some places like content type group but when adding a section we are redirected to the list. We should decide how enter should work and implement it wherever we can use enter to send a form.
