tests: set old git default branch name for compatibility

Git's default branch name has changed on my machine (from "master" to
"main"). Let's set the old name in our tests so we're compatible with
both defaults (and maybe still compatible with Git versions that don't
know about the config option).

Differential Revision: https://phab.mercurial-scm.org/D9470

This test file aims at test topological iteration and the various configuration it can has.

  $ cat >> $HGRCPATH << EOF
  > [command-templates]
  > log={rev}\n
  > EOF

On this simple example, all topological branch are displayed in turn until we
can finally display 0. this implies skipping from 8 to 3 and coming back to 7
later.
