t6429: remove switching aspects of fast-rebase

Browse source 
At the time t6429 was written, merge-ort was still under development,
did not have quite as many tests, and certainly was not widely deployed.
Since t6429 was exercising some codepaths just a little differently, we
thought having them also test the "merge_switch_to_result()" bits of
merge-ort was useful even though they weren't intrinsic to the real
point of these tests.

However, the value provided by doing extra testing of the
"merge_switch_to_result()" bits has decreased a bit over time, and it's
actively making it harder to refactor `test-tool fast-rebase` into `git
replay`, which we are going to do in following commits.  Dispense with
these bits.
