test: enable skipped login test that's incompatible with remocal

This test: https://github.com/influxdata/ui/blob/master/cypress/e2e/cloud/home.test.ts#L16 is skipped because it is incompatible with remocal. In remocal, dex is hosted at an alternate domain and Cypress freaks out when the app attempts to redirect the user to this other domain and fails the test. We need to figure out an alternate way to test this functionality or work with the deployments team to host dex under the same domain.
