ISSUE #4548 - Smart group value fields only get autofocus when adding a new field

[The-Daniel]

This fixes #4548

Description

When you create a filter for a smart group the autofocus is now on the name field
When adding a value field the input is focused

Test cases

Create a new smart group filter

• The autofocus should initially be on the name
• Adding new value fields should set the focus to the new field
  Edit an existing smart group filter
• The autofocus should still be on the name no matter how many value fields exist
• Upon adding new value fields the focus switches to the new field input
