tests: repair GITSENDEMAIL test on Windows

jpgrayson · jpgrayson · commit 56f97100c701 · 2023-04-26T15:09:36.000-04:00
On Windows, running `git send-email --help` unhelpfully opens a browser
window to an HTML version of the man page. Using '-h' avoids browser
interactions, but always returns failure (1). Using --dump-aliases is used
as an alternative, side effect free test.
