Adding punctuation to the end of a slug doesn't update the slug field

Issue Summary

If you add punctuation to the end of a slug (slug!) so that the server replies with slug-2, the slug field doesn’t update and the post is not saved.

Steps to Reproduce

1. Open web inspector so that network requests are recorded
2. Open a post in the editor
3. In the settings menu “Post URL” field, add punctuation to the end of the text then click off of the input so it updates
   • eg, if the existing slug was hello, you would put hello! in the URL field
   • there should be a GET request to get a slug from the server, if you look at the response it should be something like hello-2
4. Note that the punctuation is still shown in the URL field and that no PUT request was made to update the post

Technical details:

• Ghost Version: 1.18.0
• Browser/OS: Chrome/macOS

@kevinansfield - I’ve investigated the issue some and here’s what I’ve found.

1. When I put hello! in the slug field, it returns hello-2
2. This code (https://github.com/TryGhost/Ghost-Admin/blob/master/app/mixins/editor-base-controller.js#L255) ensures that the put request to update the slug does not occur,

        // if the candidate slug is the same as the existing slug except
        // for the incrementor then the existing slug should be used
        if (isNumber(check) && check > 0) {
            if (slug === slugTokens.join('-') && serverSlug !== newSlug) {
                this.set('slugValue', slug);

                return;
            }
        }

I’m not sure what the expected behaviour is here. The original change there was made as part of this commit - https://github.com/TryGhost/Ghost-Admin/commit/e772430bd6ac8d32ba4029e96087c53e261c182a#diff-30dc1eff6ae6709c67989797bd574a92
