Resetting saga in hacker-news example generates redundant events

[Roman Chistokhodov]

To Reproduce

1. Run hacker-news via yarn dev.
2. Click login and create new account.
3. In other terminal run yarn module-admin sagas reset UserConfirmation multiple times.
4. Check the sqlite database, you'll see a number of _RESOLVE_SYS_SCHEDULED_COMMAND_CREATED_ events (depending on how many time you called a reset)

Another (probably related) issue. If you reset SCHEDULER via yarn module-admin sagas reset _SCHEDULER_ before UserRejected is produced, the hacker-news will have unhandled promise rejections afte a while (the number of unhandled rejections depends on the number of UserConfirmation resets).

Can't reproduce anymore. Seems to be fixed in #2176
