[RCD] Expanded threads lost when switching back to message view

One of the most annoying things I've found so far in roundcube is that if you have a threaded message listing and have expanded a thread, that this when returning to the message listing from viewing a full message in this thread. It is obvious enough why it works this way but it would be fantastic if the message listing state (and position) was preserved so users don't have to search around in the message listing to to pickup where they left off.
