Cypress test for basic dynamic assignment e2e test

[schuyler1d]

Cypress test for a basic campaign with assignment is in __test__/cypress/integration/basic-campaign-e2e.test.js -- it would be good to make another file and add to automated testing the same thing for dynamic assignment -- as well as testing a campaign and texting workflows more robustly
