Deal_with_drafts

[ghost]

Hey !

We found an error during our utilisation of Melusine.

When we use the function get_emails() to load the emails, it will raise an error if it encounters a draft.

Some drafts have no sender or datetime_sent attributes, so it will raise an error in the function _extract_email_attributes().

I will join a PR with the solution we proposed to deal with drafts in the file tree.
For each email, we look if it has a datetime_sent and sender attributes. If it's not the case, we replace these attributes by None values.

If you have other ideas to deal with this issue, we are listening !

We already told the users of the mailbox to delete drafts in the file tree or move them in the folder "Brouillon".
But It may be safer to have a way to deal with a draft forgotten in the file tree, instead of having our script for the training of the DL model (which can be long) failed because of one draft.

Best regards,

Maxime
