We used to include canonical meta tag on `/c/plugin ` page but (I think) this was regressed 4 months ago when we introduced “Default Topic List” category setting.

This should now be fixed, and a test case is added to prevent future regression.

[https://github.com/discourse/discourse/commit/72c92b0f4e2c324a9902613c9464fc45bf7fc09b](https://github.com/discourse/discourse/commit/72c92b0f4e2c324a9902613c9464fc45bf7fc09b)

Now all the category pages should have canonical meta tag except the Top category page (`/c/plugin/l/top`).
