[v2,07/10] fetch+push tests: have tests clean up their own mess

Commit Message

Ævar Arnfjörð Bjarmason March 7, 2022, 12:43 p.m. UTC

Change the "t5516-fetch-push.sh" test code to make use of
"test_when_finished" to remove data instead of having tests clean up
leftover data from earlier tests, which may or may not be
there (e.g. depending on the --run=* option).

Before this each test would have been responsible for cleaning up
after a preceding test (which may or may not have run, e.g. if --run
or "GIT_SKIP_TESTS" was used), now each test will instead clean up
after itself.

When doing this split up the "push with negotiation" test, now the
middle of the test doesn't need to "rm event", and since it delimited
two halves that were testing two different things the end-state is
easier to read and reason about.

While changing these lines make the minor change from "-fr" to "-rf"
as the "rm" argument, some of them used it already, it's more common
in the test suite, and it leaves the end-state of the file with more
consistency.
