topic: add the changelog argument to branchinfo()
47c03042cd1d in core added a changelog argument to revbranchcache.branchinfo()
and we wrap that function in topic extension. So let's add this optional
argument in topic extension too.

evolve: adapt for changed @command decorator
Core changed the hacky "^command" syntax to be a proper decorator
option in fa88170c10bb (help: adding a proper declaration for
shortlist/basic commands (API), 2018-10-12). This patch makes evolve
compatible with that.
