SessionState never unlocked

[mbono]

The step to reproduce the problem:

• Start a VM in "headless"
• When the state is Running I stop it

The session state never go back to Unlocked.

Attached a .cpp that reproduce the problem.

From the log I see:

00:00:01.819978 Changing the VM state from 'DESTROYING' to 'TERMINATED'
00:00:01.824010 Console: Machine state changed to 'PoweredOff'
00:00:01.937393 VBoxHeadless: starting event loop

I suspect that VBoxHeadless do not exit becaus the event loop is started after the machine go to PoweredOff.

Using a "gui" session type do not reproduce the problem.

In VirtualBox 6.0 this works as expected also for "headless" session type.
