Interview completed email notification should not be sent if action was taken on the Job Candidate

[maxceem]

We have email of type 'taas.notification.interview-awaits-resolution' which is sent 4 hours after interview start time to remind manager to take an action on the candidate after the interview https://github.com/topcoder-platform/taas-apis/blob/revert-532-feature/revert-splitting-email-templates/src/services/NotificationsSchedulerService.js#L276-L334

Though if manager already took action, such reminder should not be sent, while now it would be sent.

Technically this means, that we have to additionally check that corresponding JobCandiate status is interview.

• Demo script https://github.com/topcoder-platform/taas-apis/tree/dev/scripts/demo-email-notifications should work good after this fix.

@sdgun this is ready for QA.

QA Guidelines:

• verify that Interview Awaits Resolution email notifications doesn't come if we approve or decline corresponding Job Candidate
• for regression, verify that if we don't approve/decline corresponding Job Candidate, then Interview Awaits Resolution would come
