[Jepsen][YSQL] No successful operations during test with kill, partition,pause nemesis

[frozenspider]

Jira Link: [DB-321](https://yugabyte.atlassian.net/browse/DB-321)
During our Jepsen on Jenkins runs, we found an issue for yb yugabyte-2.7.1.0-b34-centos-x86_64.tar.gz default-value nemesis kill,partition,pause, which corresponds to YB @ 67dac20 using yugabyte/jepsen@29471e9.
Logs are here: 20210324T102847.000Z.zip
Possibly this is another symptom of #7729

UPDATE:
kill nemesis alone is enough.

Still reproducible after #7729 fix (YB @ c9e64df):

[frozenspider]

Simplified that to just kill:

...or even just kill-master (but seems like killing both increases reproduction rate). Killing just tserver doesn't work though.

@frozenspider Is it actual inconsistency or some other kind of bug?

[frozenspider]

After looking into the logs, none of the "analysis invalid"s are caused by an actual detected inconsistency, but instead by an absence of a confirmed-successful operations, mostly CREATE TABLEs and INSERTs.
This is not okay, but it's not a consistency violation.

Looks like it's similar problem #10911
