Some recent work to convert RB.PaginationView to ES6 resulted in a

const variable that was defined in one scope and accessed in another.

This resulted in a problem building URLs needed for pagination and

switching commits.
This change fixes up the scoping issues, and also fixes a check that

resulted in the wrong variable being accessed when determining the kind

of result to return.

Verified the regression, and tested with the fix. URL building and

links worked.
JavaScript unit tests pass.
