When using the feature "create new subfolder during drag" with the quickMove
function the dropdown only suggests "create new folder" after pressing the
Slash if a real foldername was [partially] entered. It does not work when the
name of a QuickFolder (Tab) is entered that is different from the foldername.

Example:

1. create a folder named "_Social Networks". then drag it to the QF tab toolbar
and create a new Tab. Rename the tab to "Social Networks".

2. Drag an email to the quickMove button

3. Type "Social/" 

Observed behavior: no menu item is shown (only ...) in the suggestions

Expected behavior: a menu item "create subfolder [account]: Social
Networks/..."

(or alternatively display the real folder name, like: 

"create subfolder [account]: _Social Networks/..."

Here QuickFolders should treat the Tabs like real folders (if they match and
have a different name as the actual folder)
