[bug] fix notification for incoming mail with several listeners registered
When setting the listeners in the IMAP Folder, we avoid setting more than one listener for the same imap mailbox (because in some situations we were registering way too many listeners). this was making the pixelated inbox registering the notification and therefore the imap mailbox not being registered. this MR also refactors the way pixelated is initialized, so that it avoid creating a second Account instance. In this way, we make sure that the pixelated mua and the imap server share the same collections for a given mailbox, and therefore any of the two is able to get a notification whenever the other adds a message to the mailbox. - Resolves: #8846, #8798
