main: defer session update until startup animation

Browse Source 
We currently call the session updated handler as soon as
the session modes are read.  This handler sets up keybindings
for leaving the overview (if a user session) and shows the
login dialog (if a gdm session).

We can't do the latter until the stage is mapped because it
takes a grab, and we don't need to do the former until the
user goes into the overview.

This commit defers processing session updates until the
the layout manager says start up is prepared.

It fixes a race condition at login screen startup now that
we don't show the stage right away.
