Only duplicate emails used to be checked when sending a mass mail.
However it is possible (e.g. using templates) to send a mass mail
to the same person containing different information.
The existing functions to allow models to specify emails
processed in the past by some other means are kept.
A new check is added in the processing that checks the full contents
of the message, subject and attachment ids.
The strings are not hashed as most situations are:
- Sending the exact same mail to everyone
-> Only need to check against one message
-> Same complexity as hashing
- Sending all different emails
-> Checking inequality of str is usually very fast
For attachments, as we cannot compare them easily.
They are ignored for the purpose of equating emails
whenever there are the same number of attachments
in the email values as there are on the composer.
This is because each email should receive its own copy
of the composer attachments. If they have a different
number of attachments, they were generated dynamically
through reports and we assume they are all different.
We can thus remove the 'document based' information
as it is implicitly infered from this check.
-------------------------
Test utils are also updated for two purposes:
1. Add optional body and attachment_name discriminents
assertMailMail assumed all emails could at least be
differentiated by subject. Our test breaks that
assumption, so we use body and attachment to find the
best-fitting email based on the data passed in.
2. Check email_formatted on recipients
When using assertMailMailWEmails, we first find the
email using the non-formatted email of the recipient.
This does not match assertSentMail which checks against
the raw email_to value, which would often be formatted.
