Subject: [PATCH] Set role to demoted if postgres isn't running and no
 recovery.conf (#757)

In really rare cases it was causing following behavior:
```

2018-07-31 10:35:30,309 INFO: Lock owner: postgresql0; I am postgresql1
2018-07-31 10:35:30,310 INFO: Demoting master during restarting after failure
2018-07-31 10:35:30,381 INFO: postmaster pid=17709
2018-07-31 10:35:30,386 INFO: lost leader lock during restarting after failure
2018-07-31 10:35:30,388 ERROR: Exception during CHECKPOINT
