[PATCH] t7817: do not depend on any specific default branch name

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

Elsewhere, we introduced support to override the default branch name in
the tests via `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME`. Therefore, we
should avoid expecting a particular hard-coded name in test scripts.

So let's rename the initial branch immediately to `main` and work with
that.

This avoids breakages in t7817 when the default branch name is changed.
