My email address got exposed when ticket's reporter was set to me

Several tickets in the MC project were set to be reported by me (grateful!), but in the history tab of those tickets, my email address got exposed to the wide public on that change, even to people who are not logged in!

Possible causes:

• Some of the hidden fields on my account might have mixed up their values
• The wrong values were changed and reported in history

Affects tickets:

• MC-127505 (fixed)
• MC-125810 (fixed)
• MC-109286 (fixed)
• MC-97190 (fixed)
• MC-46584 (fixed)
• MC-9551 (fixed)
• MC-4057 (fixed)
• MC-2591 (fixed)
• MC-791 (fixed)
• MC-201 (fixed)
• MC-2023 (new)

Does NOT affect ticket:

MC-1531 (owned by someone else)
