Unrelated to life, but not sure if we want to generalize the `isSync` detection stuff. It looks like we've copy/pasted it +/- 5 times in the code.

```bash
$ grep -ir "isSync:" app
```

| FILE | CODE |
|----|----
| app/scripts/views/change_password.js: | `isSync: Session.service === 'sync'` |
| app/scripts/views/complete_reset_password.js: | `isSync: Session.service === 'sync',` |
| app/scripts/views/delete_account.js: | `isSync: Session.service === 'sync',` |
