tests: show how `hg split` can put color codes in commit template
With D9255, I made it so `hg split` respects the
`commmand-templates.oneline-summary` config. I don't think I realized
that the output I modified was being put in a commit message
template. The result was that if you have coloring enabled, you get
colors in the commit template. This patch show that. The test is
unfortunately pretty verbose (like most other `hg split` tests) and
shows a bunch of irrelevant "color codes" (templater labels).
