Problem: When using Insert mode completion but not actually inserting
anything an undo item is still created. (Tommy Allen)
Solution: Do not call stop_arrow() when not inserting anything.
It is otherwise impossible to determine which test failed sanitizer/valgrind
check. test/functional/helpers.lua module return was changed so that tests which
do not provide after_each function to get new check will automatically fail.
Having a tags file in the calling directory of make test would make this test
fail, so disable tag file completion for it. Disable all other options except the
current buffer, to, applying the principle of least surprise.
