Org/Space user count not updated after changes

The user counts in org and space summary pages aren't updated following adding/removing user roles to that org/space

To reproduce

• nav to an org/space summary (note user count)
• nav to user table and add/remove a user
• nav back to org/space summary and user count has not been updated

Notes

• user count comes from fetchTotalUsers --> fetchTotalResults, which creates a pagination section and populates the usual way
• reducer userSpaceOrgReducer ensures that add/remove actions also update request data user info
• nothing happens to the pagination section
  • need an effect to clear specific pagination sections

Start with fetchTotalUsers and fetchTotalResults, then inspect userSpaceOrgReducer and the pagination sections involved in org and space summaries. Done means the summary user count updates after adding or removing a user role, including when navigating back from the user table.
