Resolve Initial Acls not being set

- instead of directly assigning the incoming $role_set to _roles we instead
  utilize the function setRoles which will take care of keeping the acls in
  sync.
- remove the initialization of _acls to an empty array() as this would override
  the work done by setRoles.

- Also needed to remove the additional acl-import in
  integration_tests/scripts/bootstrap.sh as we need to see if the changes made
  to XDUser work as expected.
