Basically, this fixes disappearing previews when editing asset metadata or performing undo/redo actions. The preview generation in a background job will eventually modify ID data, but the undo push was done prior to that. So obviously, an undo then would mean the preview is lost. This patch makes it so undo/redo will regenerate the preview, if the preview rendering was invoked but not finished in the undone/redone state. The preview flag PRV_UNFINISHED wasn't entirely what we needed. So I had to change it to a slightly different flag, with different semantics.
