[PATCH v1 1/4] t1092: add tests for `git-rm`

[Shaoxuan Yuan <shaoxuan.yuan02@gmail.com>]

Add tests for `git-rm`, make sure it behaves as expected when
<pathspec> is both inside or outside of sparse-checkout definition.

Also add ensure_not_expanded test to make sure `git-rm` does not
accidentally expand the index when <pathspec> is within the
sparse-checkout definition.
