Yoast is not pinned in Gutenberg sidebar by default

[dariaknl]

The issue comes from version which is still not released by Gutenberg, I was not able to find when they want to release.

How can we reproduce this behavior?

1. Checkout gutenberg version from master branch.
2. Activate gutenberg.
3. Install and activate Yoast SEO 13.4.1..
4. Start creating new post in incognito browser (to make sure all settings are default)
   You see that Yoast is not pinned anymore:

5. Click Tools and see that Yoast appears in Plugin section:

6. Click Yoast, and you get Yoast sidebar, but it is still not pinned in toolbar:

7. Click to pin ("star") on top, then you get Yoast sidebar pinned in toolbar:

Problems:

1. If we can get Yoast SEO pinned in toolbar by default (as it is now) - that would be good. Otherwise our plugin in sidebar is not visible anymore, especially for customers who are not active users of Gutenberg.
2. Another issues is related to Plugin session which you see in step 5: Yoast plugin used to have Y logo there, but it got lost and is not shown anymore (this is also reproduce in 7.8.1)

Also:
in the Tools menu > Plugin section, there should be an icon close to plugin name. It is missing.

Left: Gutenberg plugin deactivated. Right: Gutenberg plugin activated:

Regarding the missing (not visible) icon: created an issue upstream. See WordPress/gutenberg#21506

This could also be solved on our side by just explicitly setting the width and height attributes on the passed SVG WPElement e.g. icon: <PluginIcon height="20" width="20" />. Reported upstream because it's a breaking change on Gutenberg master.
