CSAT survey not being sent when reporter is added as a watcher

Issue Summary

A change has been made in which when a reporter is added as a watcher they will only get internal notifications.

Because of this, tickets in which the reporter who is also a watcher in the ticket, are not sending CSAT Surveys even when the option is enabled. 

(The survey is sent on the customer notification for the resolution - which is now not sent in this case) 

Steps to Reproduce

1. Create a ticket and add the reporter as a watcher
2. Resolve the issue
3. Check the reporter email - no CSAT survey

Expected Results

CSAT survey being sent

Actual Results

No CSAT survey is sent

Workaround

Remove the reporter from the watcher list before resolving the ticket
