sparse-index: update command for expand/collapse test

vdye · gitster · commit 86609db9dae7 · 2021-10-27T15:05:11.000-07:00
In anticipation of `git reset --hard` being able to use the sparse index
without expanding it, replace the command in `sparse-index is expanded and
converted back` with `git reset -- folder1/a`. This command will need to
expand the index to work properly, even after integrating the rest of
`reset` with sparse index.
