t4205: drop top-level &&-chaining

The test currently does something like: do_one() && do_two() && test_expect_success ... We generally avoid performing actions at the top-level of the script (outside of a test_expect block) for two reasons: 1. The test harness is not checking and reporting if they fail. 2. Their output is not handled correctly (not hidden by default, nor shown with "-v"). Using &&-chains seems like it should help with (1), but it doesn't. If either of the commands fails, we simply skip running the follow-on test entirely, and the test harness has no idea. We can fix this by pushing that setup into its own block. It _could_ go into the following test block, but since the result in this case is used by multiple tests, it's more clear to mark it explicitly as a distinct setup step.
