Find Contributions : Send Email to Contacts Task - Emails are duplicated in recipient list of the contact appears more than once in resultset

Find Contributions - If your search criteria returns multiple contributions from the same contact - and you use the "Send Email to Contacts" task - then the "Send Email" recipients list will include that contact's email address multiple times. This is confusing to the user (and if we're sending the email to that contact multiple times - then it's also bad behavior for the constituents).

I've also recreated this behavior from Find Memberships (and I expect it will also be present in Find Participants).
