Remove unnecessary `This email has been sent to ###EMAIL###` from privacy emails.

[iandunn]

Several privacy related emails contain a string in the body saying, This email has been sent to ###EMAIL###. It appears that this was copied from the emails that get sent when an email address changes, without considering if it made sense in the new context.

I think that string is appropriate in the original use cases, because explicitly calling out the receiving address can help avoid confusion, since the address is changing.

The string is not used in any other emails in Core, though, except for some of the new privacy ones from 4.9.6. I think the string is unnecessary in the new context, and it's best to remove it.

The recipient address is already obvious enough from the To header, and removing unnecessary content will make the messages shorter, and maybe even avoid some suspicion from spam filters, which sometimes penalize seemingly innocent text, especially if it contains URLs or email addresses.
