Files (Nautilus) does not appear in Launcher or Alt-Tab

Bug Description

When Nautilus is unpinned, it does not show up in the Launcher, even when it is running. It does not show up the list displayed by alt-tab either. Even when Nautilus is pinned, it does not indicate (with a tiny arrow to the left of the icon) that it is running, and clicking on the icon in the launcher doesn't switch to it.

This is regression from bug #1578792.

I'm on a fully updated 16.10 and I don't experience this bug. Unpinned Nautilus appears on launcher and in Alt+Tab switcher.

It also works in 17.04 LiveCD.

I can confirm this bug (again) in Ubuntu 16.04 too with all updates installed.

I checked today the daily image of 16.04.1 LTS and there also everything works as expected.

The version of Unity is 7.4.0+16.04.20160906-0ubuntu1.

This is an unsupported release now. Please think to install the next LTS 'Bionic 18.04'
