[PATCH] t2028: fix minor error and issues in newly-added "worktree move" tests

[Eric Sunshine <sunshine@sunshineco.com>]

Recently-added "git worktree move" tests include a minor error and a few
small issues. Specifically:

* checking non-existence of wrong file ("source" instead of
  "destination")

* unneeded redirect (">empty")

* unused variable ("toplevel")

* restoring a worktree location by means of a separate test somewhat
  distant from the test which moved it rather than using
  test_when_finished() to restore it in a self-contained fashion

This patch is built atop nd/worktree-move-reboot in 'next'.

I didn't get around to doing a proper review of nd/worktree-move-reboot
v2 [1] until after it had graduated to 'next'. Although v2 fixed all the
issues identified in my review of v1 [2], it introduced a few minor
issues of its own. This patch addresses those issues.
