QuickFolders + quickMove fails to invoke the assistant

[RealRaven2000]

When moving one or multiple mails using the QuickFolders quickMove functionality (by dragging tot he quickMove / quickJump button or via the shortcut Shift+M), apparently the filter assistant will not show up.

Reference bug see here:

RealRaven2000/QuickFolders#385

So it seems like there is something different in the message database, I was using the target folder (the folder that the email was moved to) in order to retrieve the current messageHdr but that doesn't appear to work, so I fixed that in this prerelease:

quickFilters-wx-6.1.2pre31.zip

To test the version above, download the zip file, drag into Thunderbird Add-ons Manager, do not extract contents or if won't install.
