Konstantina Chremmou fc98eed16b CA-237915: When one attempts logging oneself out, warn them if there are outstanding actions. 
For this purpose, call the DisconnectCommand instead of session.logout_subject_identifier.
Also:
- Add the new actions to the History synchronously on the main thread,
otherwise the warning dialog may not detect in time the new actions.
- Although the local root account is currently first in the list, checking whether
the first item is selected is a fragile way of establishing whether the local
root account is selected. Check the row's IsLocalRootRow property as in the
rest of the file.
- Added username detail to the logout action; fixed typo in message key.
- Some minor refactoring to make the code more efficient.
