Admin "Recent Actions" should differentiate between Sites

[Arthur Koziel]

If I set up two Sites which share the same database but use the Sites framework to assign content to a specific site, the "Recent Actions" Sidebar doesn't distinguish between different Sites. Content created and assigned to a specific Site will show up in other Sites "Recent Actions".

Steps to reproduce:

1. Set up two different Sites which share the same database
2. Create an entry and assign it to Site A
3. Open up the Site B Admin

Expected:
"Recent Actions" should only show those entries assigned to the current Site.

There's nothing special about the site model that'd warrant special treatment in this way. If you need this kind of behavior, create a custom admin index.html template and override the parts as needed for your own site.
