loc_handlers git: fix potentially flaky test t/rose-app-run/28-git.t

[oliver-sanders]

Good news, the tests pass.

Bad news, if some of the tests skip, then the test fails, e.g:

diff --git a/t/rose-app-run/28-git.t b/t/rose-app-run/28-git.t
index 1b4eaaa90..92a411611 100644

     fi
-    if [[ "$remote_mode" == "http" ]] && ! curl --head --silent --fail $remote >/dev/null 2>&1; then
+    if true; then
         skip 14 "failed to launch http on localhost"
         echo "Skip $remote" >/dev/tty        
         continue

:(

  Non-zero exit status: 1
  Parse errors: Bad plan.  You planned 57 tests but ran 42.

Not a release blocker. Suggest bumping this to future work.
