Merge branch 'js/t2106-cleanup'

A test script got cleaned up and then made not to depend on the
value of init.defaultBranch.

* js/t2106-cleanup:
  t2106: ensure that the checkout fails for the expected reason
  t2106: make test independent of the current main branch name
  t2106: adjust style to the current conventions
