Issue #1839924 by greg.1.anderson: Update previous fix to work on D8 again (check for package Core before other tests)

Tighten conditions under which we write a sites.php file during site-install. Trying to avoid permission errors for most folks in a locked down environment.

Fix field_create_instance() call in field-create command by introducing drush_call_user_func_array() which can call into a function that takes a reference instead of a value.

For browser opening, don't check the DISPLAY environment variable when running in simulate mode, so we can test consistently.

Improve isolation of complete tests, to avoid incidental breakages when adding/removing core commands.
