Proposed updates

- Failing cuke in `projects.feature:172` is passing. 
- Added `WaitForAjax` module in `helpers.rb`. 
- Minor change in `_members_list.html.erb` 
  - removed `presenter.title_list` and changed html tag on `presenter.country` from `<p>` to `<small>` 
nice! i had tried wait_until but it was deprecated. Didn't know about wait_for_ajax :+1:
