Changed

1. Fix issue with Content Collection when reading ES total value. It used to be an integer, but is now an object with a "value" property. This should fix issues with pagination not displaying and the total result description not displaying.

@dylankelly this looks very non contentious to me but could you run a quick eye over it if you get a chance. This PR is just going against another test PR so can merge this safely and review later if you prefer.
