[5.x]: Use field handle instead of field name after field creation in searchbox

[jeroenlammerts]

After creating a new field in the field layout view, the searchbox is filled with the field name to search the new field.
When having multiple fields with a title like "Text", multiple fields are found.
Is it possible to fill the search box with the field handle, than only that field will be visible.

We’ve made some changes to field layout designers for Craft 5.6 that resolve this (#16374). Going forward, newly-created fields are automatically added to the tab they were created from.
