Bug 1753696 - move common setup/init tasks in head.js files to use add_setup, r=Standard8

Without this, changing to add_setup in individual test files causes the tasks to be reordered, which causes tests to fail.

I also had to adjust an enterprise policy test that was expecting setup tests to run inbetween tasks.
