[PATCH v6] tests: use test_path_is_missing instead of '! test -f'

[Jayesh Daga <jayeshdaga99@gmail.com>]

From: jayesh0104 <jayeshdaga99@gmail.com>

Using plain "test" commands in a sequence of checks chained
with `&&` makes it difficult to determine which step failed,
as "test" silently succeeds or fails.

In this case, we expect that `.git/refs/heads/f` no longer
exists. Replacing `! test -f` with `test_path_is_missing`
preserves the expected behavior when the file is absent,
but provides a clearer diagnostic when it unexpectedly
exists, making test failures easier to debug.
