Rider self-service portal ride request appears active even after rider has cancelled ride

[sasjkia]

Steps:

• Rider signs up. UUID: 6ffc525d-e69e-4018-90ca-f9b6ad91428f.
• Rider cancels ride request via SMS link, before any match has been confirmed.
• Rider is able to log into self-service portal. The self-service page claims that the rider has a confirmed match.
• Rider receives cancellation notice via both SMS and email.
• Rider is able to cancel the ride request a second time through the self-service portal.
• When logging in again, the self-service still states that the rider has a confirmed match.

Please can we change this to the following:

• When rider cancels the request, they receive notifications via their preferred contact methods only (see backend issue #144 for more on this).
• After cancellation, they are able to log into the self-service portal to reactivate the ride request through a green button stating "Reactivate ride request".
