[PATCH v2 1/4] t3404-rebase-interactive: use the 'q_to_cr' helper

["SZEDER Gábor" <szeder.dev@gmail.com>]

The test 'rebase -i respects rebase.missingCommitsCheck = warn' checks
the output of 'git rebase', including progress lines: it prepares the
expected output from a here-doc using LFs at the end of progress
lines, and converts the command's actual output by replacing the
progress lines' CRs with LFs with a one-shot local helper funcion.
Similar tests (in t3420) thoroughly checking 'git rebase's output do
it the other way around: they leave the output of 'git rebase' as-is,
and prepare the expected output with the necessary CRs in it using the
common 'q_to_cr' test helper function from 'test-lib-functions.sh'.

Change this test to use the 'q_to_cr' test helper to prepare the
expected output, too.

This way this test will be more consistent with other, similar tests,
and it will make further updates to this test in a later patch of this
series just a tad bit simpler.
