Comment (by subrataemfluence):

 I could reproduce the issue in 4.7.4. I created two posts entitled "40588
 Test" and "40588 Test 2" and saved them both as Draft. After trashing and
 restoring the permalinks changed to `"__trashed"` and `"__trashed-2"`
 respectively. Means this holds true for 4.7.4 as well and not specific to
 version 4.5.

 However, there is always a chance of WordPress replacing slugs of trashed
 posts after restoration because it has to check whether the same permalink
 (which the restored post originally had) is already present with other
 posts. For a huge database it would be resource consuming to search the
 entire `WP_Posts` table and then come up with a relevant permalink based
 on its title. It is always a better option for the admin to edit the
 permalink once it is restored.

 Nevertheless, the permalink could be replaced in a better fashion after
 restoration like `post_id-restored` (e.g. 786-restored) if suggesting one
 is not the best option.

 When trashed WordPress is actually replacing the permalink to `__trashed-
 xx`, so it would not be very unlikely that when it is restored WordPress
 does the same thing for one more time to make it like I mentioned.
