Amend the tests checking whether stderr is empty added in
4868b2ea17b (Subject: setup: officially support --work-tree without
--git-dir, 2011-01-19) work portably on all POSIX shells, instead
suppressing the trace output with "test_untraceable" on shells that
aren't bash.
The tests that used the "try_repo" helper wanted to check whether git
commands invoked therein would emit anything on stderr. To do this
they invoked the function and redirected the stderr to a "message"
file.
In 58275069288 (t1510-repo-setup: mark as untraceable with '-x',
2018-02-24) these were made to use "test_untraceable" introduced in
5fc98e79fc0 (t: add means to disable '-x' tracing for individual test
scripts, 2018-02-24).
It is better to have the "try_repo" function itself start with a
"test_when_finished 'rm stderr'", and then redirect the stderr output
from git commands it invokes via its helpers to a "stderr" file.
This means that if we have a failure it'll be closer to the source of
the problem, and most importantly isn't incompatible with "-x" on
shells that aren't "bash".
We also need to split those tests that had two "try_repo" invocations
into different tests, which'll further help to narrow down any
potential failures. This wasn't strictly necessary (an artifact of the
use of "test_when_finished"), but the pattern enforces better test
hygiene.
