ctrlAltTab: don't allow more than one popup

In a normal user session you can't have more than one
popup, because the popup is modal and we don't allow
the popup to show up when there are other modals.

In a GDM session, however, the login dialog is modal, and
we want a popup, so we don't have that same check.

This commit changes the ctrlAltTab manager code to not
allow multiple popups.
