Email Preferences - round out options for Projects and Phriction

Summary: Fixes T8524, T8550. These were both missing "subscribers" and Phriction was also the only application with no "other".

Test Plan:
 - Project
   - set user A to notify only for project subscriber changes
   - made a project with user A
   - subscribed user B to project
   - verified notification sent to user A
   - used ./bin/mail to make sure no mail was sent to user A because "This mail has tags which control which users receive it, and this recipient has not elected to receive mail with any of the tags on this message (Settings > Email Preferences)."
  - Phriction
   - set user A to notify only for phriction document subscriber changes
   - made a document with user A
   - subscribed user B to document
   - verified notification sent to user A
   - used ./bin/mail to make sure no mail was sent to user A because "This mail has tags which control which users receive it, and this recipient has not elected to receive mail with any of the tags on this message (Settings > Email Preferences)."
   - observed option for "other" in email preferences
