Fix crash in plugin when installing host from WebApp (Windows)

The crash happens when |DaemonControllerDelegateWin::
OnInstallationComplete| runs the |done| callback which was passed as an
argument:

- |done| is passed by reference
- |done| is owned by the caller |installer_| (as a bound
parameter of |done_|)
- |installer_| is destroyed before |done| runs
- |OnInstallationComplete| runs |done|, which now points to released
memory, and crashes

As far as I know, this problem has existed for a while. It should crash
consistently in DEBUG where released memory is wiped out. It might have 
been working in RELEASE due to sheer luck.

V2 app is showing up on incorrect users desktop upon user session restore

Git apparently removed a few lines my last merge (it appears not to be a good idea to do multiple depending CL's in parallel)...

The problem was that the AddUser event which I added did not get properly dispatched to MultiUserWindowManager.
