[4.x]: Empty query string in preview target URLs

[mmikkel]

What happened?

Description

Preview target URLs will always have an ? (i.e. an empty query string) appended to them, even if there isn't a query string in the "URL Format" setting for that preview target.

Steps to reproduce

1. Create a section and add a preview target to it with a "URL Format" that doesn't include a query string – for example, {url}
2. Create an entry in that section
3. Click the "View" button in entry's edit page to open the preview target URL in a new browser tab
4. Observe that the URL has an empty query string (i.e. ?) appended to it

Expected behavior

No question mark appended to the URL unless the preview target's URL format has a query string.

Actual behavior

There's a question mark appended to the URL even if there isn't a query string in the preview target's URL format.
