Using a focus phrase of more than two words seems to break the URL-check for the focus keyword

[tacoverdo]

Example
Create a new post with the following details:

• Title: bali immigration office
• Content: bali immigration office
• Focus keyword: bali immigration office
  This should result in the following URL, if permalinks are set to post title:
• http://example.dev/bali-immigration-office/

Checking the URL for the focus keyword returns this:

The focus keyword does not appear in the URL for this page. If you decide to rename the URL be sure to check the old URL 301 redirects to the new one!

Now change the focus keyword to bali immigration. The check should now recognize the focus keyword in the URL.
