Show the email address of the recipient on all activities on folders shared via mail (rather than `remote user`)

Steps to reproduce

1. Share a File via email
2. Open the activity log for the shared file / folder
3. Watch the activities that are not consistent in their message.
   

Expected behaviour

The activity app shows the mail address of the recipient on all activities and not only on downloads.

Actual behaviour

• The activity app shows "was created in a public folder" when a file / folder is created in the shared directory
• The activity app shows "remote user" when a file is renamed or deleted
• The activity app shows the actual email address when a file is downloaded.

Reproduce the issue from the activity log for a file or folder shared by email, comparing creation, rename, deletion, and download activities. Trace the activity handling for email-shared folders; done means every listed activity displays the recipient's email address instead of “remote user” or “public folder,” without changing the existing download behavior.
