Added refresh to publishing test (#19612)

refs ENG-599
- added refresh to publishing workflow test
- member count is cached and not updated immediately upon adding a
member, but a count >0 is required in order to send a newsletter (what
this test tests)
- we are looking at updating the cached count; until then, a refresh
will be a performance hit but allow this test to pass
