Service registered using `/v1/catalog/register` are removed during anti-entropy sync

Services registered using `/v1/catalog/register` get removed during the anty-entropy sync. As far as I can tell it does not happen when using the agent endpoint.

I noticed this will looking into https://github.com/terraform-providers/terraform-provider-consul/issues/187

#### Reproduction Steps

```
$ consul agent -dev >consul.log &
[1] 41646
$ curl -X PUT -d '{"Node":"Remis-MacBook-Pro.local", "Address":"127.0.0.1", "Service":{ "Service":"redis", "Port":6379}}' http://localhost:8500/v1/catalog/register

true
$ curl http://localhost:8500/v1/catalog/services
{
"consul": [],
"redis": []
}
$ curl http://localhost:8500/v1/catalog/services # one minute later
{
"consul": []
}
```

### Consul log
