We should remove script_exec test dependency on examples/a* and examples/b*

Created by: aimof

Description Always when we try to change integration test which file name starts a or b, we must change examples/script_exec.out.

Expected behavior Tests should not depend on each other.

Actual behavior script_exec test depends on a* and b*.

Blocking/related When I write a test to #638 (closed), i notice this problem.

Misc I'll make a PR.
