Bug fix: reset ctx->vsize in update_index_unthreaded on reopened mailbox

This fixes a bug observed when doing the following:
1. Start Mutt on some mailbox.
2. Limit the view.
3. Set sort by date (thus unthreaded).
4. Set $status_format to display the size of the messages shown (%L).
5. Copy a message matching the limit pattern to this mailbox.
6. With another Mutt instance, remove this message from this mailbox.
7. Move the cursor to update the view.
Result: one was getting a value equal to twice the initial size.
