Addresses not added to "CC" when replying to emails with multiple "To" addresses

[ojs87]

Issue

When you hit "Reply To All" to an email in SuiteCRM, if the email has a second address in the "To" field, this address doesn't get added to the CC field.

Expected Behavior

You would expect the reply to send to this address as well, or at least add it to the CC field by default

Actual Behavior

Only the "From" address and any CC in the original email gets added to the new email.

Possible Fix

Add any address that isn't the address that the email was sent to to the CC field.

Steps to Reproduce

1. Open up an email that has multiple "To" addresses
2. In the Action menu, hit "Reply To All"
3. Only the "From" address will be added to the new email and the additional "To" addresses will be ignored.
