Hide the paging controls in Chargeback -> Assignments -> Storage

The call to the 'cb_rates_list' method applies to the Rates accordion
only and should not be called in explorer since that fetches the
chargeback rates list and displays a paging control at the bottom of
the 'Assignments' page where the paging controls are not applicable.

Let URI build the URI since hostname= auto-wraps an ipv6 address in [].

Fixed spec/requests/ authentication specs

- Update session_store to use :memory instead of default cookie_store for tests,

PR Review Updates

- Simplified check in session_store initializer
- Reverting auth_specs tests as earlier.
