progress: react more reasonably to nested progress topics

Previously, we'd reset the entire progress bar state when a topic was
completed, even if it wasn't the outermost progress topic. Now we
print the state of the next progress topic on the stack if one is left
rather than reset the progress bar.

Failed qimport of patches from files should cleanup by recording successfully
imported patches in series file.
