Fix reading message id and size when returned in reversed order by IMAP server

[MattiLehtinen]

Fixes IMAP to work with Office365 (outlook.office365.com) when using DJANGO_MAILBOX_MAX_MESSAGE_SIZE option.

To reproduce:

• Create office365 mailbox
• Use it with django-mailbox using IMAP
• Set DJANGO_MAILBOX_MAX_MESSAGE_SIZE
• Expected: mails are fetched
• Actual: no mails are fetched

This is because when using Office365 IMAP, the server returns
['1 (RFC822.SIZE 45274 UID 84)']
instead of expected
['1 (UID 218 RFC822.SIZE 4680)']

@Pietro395 as you are using office 365, please could you check if this is still the case or not?
It looks like a non standard implementation that may have been fixed on their side since...

On the tenants to which I have access I have never been able to access via IMAP, for this reason I have implemented access to the folder via API, I don't think I will be able to try this case unfortunately
