FakeDriver: adding and removing instances on live migration.

Browse Source 
There was no code in FakeDriver that updated the internal
dict `self.instances` when a FakeInstance was live migrated.
This commit fills this gap. As a result, a couple of versioned
notification samples get updated since we are now properly
tracking a live migrated instance on the destination host as
running vs pending power state.
