Separate updates of Instance and InstanceDetails

Some updates for instances trigger instance details updates, while other
updates to instances are not visible on instance details. Rename
instanceUpdated to instanceDetailsUpdated to better represent what it
does and only set instancesDirty when an update is made to the
instances.
