Koni Marti c6463ba481 msgview: enable next/prev with unfetched headers
Fix message view behavior for unfetched headers. When scrolling "over"
the message list boundary, current behavior is to close the message
viewer tab. Now, the headers will be fetched so that we can scroll
through the messages uninterrupted.
