[FIX] account: allow xls,xlsx,csv attachment from alias

Set up email alias for Vendor Bill journal
Send email with xls attachment to alias
Bill is created
Issue: No attachment is present

This occurs because after 9b735f7
the system will not add binary attachments to the created bill
The change was meant to filter out rogue images often present in emails
but it is too restrictive so this commit add a second check with
the mimetype of the parsed attachment in order to keep useful
attachments
