evolve: respect command-templates.oneline-summary if configured

Mercurial has a new `command-templates.oneline-summary` config that is
respected by `hg rebase`, `hg phabsend`, and the bundled version of
`hg split`. This patch makes `hg evolve` also respect it. Unlike the
upstream commands, I let `hg evolve` use the existing template by
default. The reason I didn't change the default is that we have a
different template when topics are enabled and it's unclear how that
should work with the default from upstream. So at least for now, the
user will have to explicitly set the new config if they want it to
apply to `hg evolve`.
