Sync problems when restarting Unity place daemons

[Mikkel Kamstrup Erlandsen]

When any of the Unity place daemons are restarted you'll see something like:

-----------
$ src/unity-applications-daemon
(process:2494): unity-applications-daemon-DEBUG: daemon.vala:346: Building initial application menu
(process:2494): unity-applications-daemon-DEBUG: daemon.vala:367: Indexing application menu
(process:2494): libunity-DEBUG: unity-place.vala:772: No browser to export

(process:2494): dee-CRITICAL **: clone_leader: assertion `self->priv->revision_queue == NULL' failed

(process:2494): dee-CRITICAL **: clone_leader: assertion `dee_model_get_n_rows (DEE_MODEL (self)) == 0' failed

(process:2494): dee-WARNING **: Transaction from com.canonical.Unity.ApplicationsPlace.ResultsModel is in the future. Ignoring transaction.

(process:2494): dee-WARNING **: Transaction from com.canonical.Unity.ApplicationsPlace.SectionsModel is in the past. Ignoring transaction.

(process:2494): dee-WARNING **: Transaction from com.canonical.Unity.ApplicationsPlace.GroupsModel is in the past. Ignoring transaction.

and the shared models will fail to sync properly. There are two issues at play here:

1) DeeSharedModel doesn't accept seqnum > 0 for its first Commit, which it should
  - This obviously needs to be fixed in Dee

2) Architecture problem between place daemons and unity shell - the shell should not hold a writable model. Can be fixed by one these measures:
  2.1) Make sure the place daemons only start updating their models *after* they've received the "notify::synchronized" GObject signal from the models.
  2.2) Implement a read-only DBus model that doesn't own the swarm name. See bug #675565
