Use vanilla redis library for User persistence

Before this change, the redis-backed Rails::Cache from the `redis-rails` gem
was used to persist the user properties across nodes. This was problematic because:

* the gem used object marshalling which ocasionally started failing (eg when the ruby version was upgraded)
* the `redis-rails` gem appears to not be maintained anymore

The new approach is to use the `redis` gem directly and to serialise the user properties as JSON.

Simplify `gds-sso` user mocking

This change sets the `gds-sso` test user automatically in development mode
whenever SSO is mocked out. This means that:
* it's no longer necessary to run a rake task once a day to run this app in development.
* 2 methods from `User` (that were only used in SSO mocking mode) can be dropped.
Update README with simplified running instructions
Rename User#create! to User#upsert!

The `User#create!` method was actually creating or updating, rather than
purely creating, and thus calling it `upsert!` is much closer to its true function.
Feedex: truncate, allow line-breaking of URLs

This stops from URLs breaking the layout of the table or taking too much space.

Bump gds-sso to 9.4.0, pick up User specs

when the `User` class is refactored or `gds-sso` is bumped.
