Magento don't create product redirect if URL key on store view level was changed.

[sergei-sss]

Preconditions

1. Magento 2.1.6 with Sample data

Steps to reproduce

1. Create store view with code "second" for Main Website
2. Create new product with name "A" for Main Website (URL Key "a"). Here are product URLs from core_url_rewrite table:
   https://drive.google.com/file/d/0B__P_POF2b9aTHU0M21zVnJ2ZG8/view?usp=drivesdk
3. Switch to "Default Store View" (store_id = 1 for me) and change URL Key to "b" then save product:
   https://drive.google.com/file/d/0B__P_POF2b9adHpDT1ZSUDRRRzg/view?usp=drivesdk

Expected result

1. 301 redirect for "Default Store View" (ID#1) in core_url_rewrites table

Actual result

1. 301 redirect missing
   https://drive.google.com/file/d/0B__P_POF2b9ael9MaWdZU0xGYVk/view?usp=drivesdk

But

If you change URL Key on "All Store View" level - 301 redirect will be created for "Second Store View" store, which haven't personal URL Key value.

Issue occurs if change URL Key on the Store View level.
