evolve: move progress-clearing out of _cleanup()
The progress is only used with --all or --rev, so there's no need to
clean it in any other case. It's therefore easier to clean it
specifically in that case.

evolve: stop passing no-op "progresscb" into continueevolve()
The "progresscb" doesn't do anything in the --continue case, so
there's no need to pass it into continueevolve().
This lets us remove the --no-all that was added to the test as a
workaround.
