Private replies should be included in the forum summary report

Setup

1. Prepare a course containing 3 editing teachers (teacher1, teacher2, teacher3) and a forum activity (forum1).
2. Login as each user, and submit the following discussion post/replies, noting the time displayed on each post (note down the time as time1):

   User	Replying to	Text
   teacher1	new discussion	Discussion1
   teacher2	Discussion1	reply1
   teacher3	reply2	reply2

1. Wait at least 1 minute, so that some time has elapsed.
2. Log back in as teacher1, and send a private reply to teacher2's "reply1", with the text "private1" (ensure you have checked the "Reply privately" checkbox).
3. Note down the time of the private reply as time2 (it should be different to the other post times from step 2).
4. Log out, and log back in as site admin.
5. Navigate to Site administration > Users > Permissions > Define roles > Teacher, and click "Edit".
6. Scroll down to the filter and search for "mod/forum:readprivatereplies".
7. Uncheck "Allow" next to that capability, and click "Save changes".
8. Log out.
