[MlMt] [BUG] Deleting Found Messages not removed from Submailbox

[Michael Nietzold]

Summary:
- when deleting Messages in a Search Result in a subfolder the Messages 
are  not removed from subfolder

where:
- 3 Pane view
- i have Smart Mailboxes with subfolders for "to -> adress"
- i click on the Subfolder
- i type a search in the search box
- i select one or more messages
- i hit delete
- i don't see the messages in the list
- i hit esc to remove the search keywords (or click on the '-')
- i see all messages

what i see:
- the deleted Messages still visible in the Subfolder
- Column "Source Mailbox" of the deleted Messages is changed to "Deleted 
Messages"
- Column "Source Mailbox" of remaing message still in the INBOX

what i exptected:
- deleted Messages are Removed from the subfolder



Steps without success
- and synchronize on the Smart Mailbox don't recalculate the Subfolder 
(what i expect in this case)
- take Mailbox offline and then online
- restart MailMate

Workaround with success:
- i need to edit the Settings of the Smartmailbox (for example to "from 
-> adress") and then change it back to my settings
- now the messages are gone from

Also tested:
- wenn i search inside the rootnode (not in a subfolder) of the same 
Smart Mailbox then the messages are removed from the list


Environment:
MailMate Version 1.12.4 (5594)
