Remove the 'here's our 6 projects' stuff from the donations thanks page

[equivalentideas]

We identified last year that donors care about one project, and aren't very interested in our other ones. Having so much information about the projects on the thank you page makes it hard to see the important transaction success stuff further down. We should remove the project list so people can focus on feeling awesome that their donation was confirmed.

Do this for each thankyou page:

• [x] PlanningAlerts
• [x] Generic
• [x] Right To Know
• [x] They Vote For You
• [x] OpenAustralia.org.au
