Issue Summary

If the Reporter is a Customer, the SLA condition "Comment:For Customers" would not trigger when a Public Comment is made.
This Bug does not affect 4.6.0
This Bug is occurring despite the Permission Scheme is set to grant 'Browse Project' permission to 'Service desk customer - portal access'.

Steps to Reproduce

1. Create a new Service Desk Project
2. Configure SLA as follows:
   • Start: Issue Created
   • Stop: Comment: For Customers
3. Create a new Issue
4. Ensure the Reporter is a Customer user
5. Login as an agent user and add a Public Comment to the ticket

Expected Results

The SLA would stop as the SLA Condition 'Comment: For Customers' is met when Public Comment is added

Actual Results

The SLA does not stop even when the SLA Condition 'Comment: For Customers' is met when Public Comment is added

Workaround

Create a Group/Project Role (e.g.: Service Desk Customers), add all the Customer users into the Group/Project Role and grant the 'Browse Project' permission to the Group/Project Role.
