Review Comment:
There is probably something specific that needs to be executed in the
`TabletGroupWatcher.run()` before this should be executed, but I'm not sure
what... When `watchersStarted` is set to true will probably have to be changed.
Currently is set after calling `start()` on all the watchers.
