When the upstream of a pipe throws an error, the downstream still executes
normally. This happens because the exit code of the upstream in a pipe is
ignored. This behavior can make debugging very hard in case a test fails.
Also, pipes are prone to deadlocks. If the upstream gets full, the commands
downstream will never start.

Write out the output of the git command to a file, so as to test the exit
codes of both commands.

Commit c6f44e1da5 (t9813: avoid using pipes, 2017-01-04) noticed that the
exit code of upstream in the pipe is ignored, thus using pipes should be
avoided.
