Launcher icons disappearing after 'Unlock from Launcher'

[Nick Dedekind]

To reproduce:

1) Start an application (eg gedit) from dash.
2) Lock application icon to launcher.
3) Close application (gedit)
4) Start application from newly locked launcher icon.
In normal instances, we should see the instance indicator showing as an arrow next to the launcher icon, but alas this is not so. This is the first issue.
5) Unlock the application icon from the launcher.
6) Close the application (gedit)
App icon will be removed from launcher.
7) Start application again from dash.

Launcher icon does not appear!!

Confirmed for me locally.

What's interesting is that apps I have had pinned to my launcher for a while work perfectly. This leads me to believe that somthing has changed in the launcher pinning code that breaks this.

The app instance is also missing from the switcher model, so perhaps this is a bamf bug?

Added a branch with an autopilot test.
