[4.x]: Need warning for duplicate slug when editing

[wbdzynr]

What happened?

Description

If you are editing an entry, and you make changes to the slug (for a desired result), it doesn't warn you if there is already an entry with that slug. It just appends a number to the end again.

Steps to reproduce

1. Duplicate an entry and try to remove the "-2" from the end, then save. If you check entry Validation isn't performed when enabling entries from entry index page. #2, it will have a "-2" at the end of the slug again.

Expected behavior

When creating a new entry, appending a number to the end of the slug is fine. However, if you are editing and you expect a slug to be a certain way (ie you edited it) and that slug already exists, it would be nice if a warning would appear (ie "An entry with that slug already exists. (Entry ID: 111).") giving you a heads up that your desired changes won't happen.

Actual behavior

Currently, it just appends a number to the end of the slug again.
