py-hg-evolve: update to 10.3.2.

This is a bugfix release. The most notable changes are: previously
changing topic of a merge commit could lose some file changes, this has
been now fixed, and `experimental.topic.publish-bare-branch` and
`experimental.auto-publish` config options should now interact with
each other correctly. To see more information about these experimental
config options, try `hg help -e evolve` and `hg help -e topic`.
