vim-patch:9.1.1681: tests: no test for actually moving cursor with 'acl' (#35452)

Problem:  tests: no test for actually moving cursor when menu is not
          open with 'autocompletedelay'.
Solution: Use <Up> first in the test. Also remove two unnecessary <Esc>s
          in completion timeout test (zeertzjq).
