TPv2 have tests use sidebar

[shamrickus]

This PR changes the TPv2 e2e tests so that they use the sidebar for navigation when possible. It also fixes an issue where the tests weren't idempotent. Finally the tests have been modified so that they will work when pointed at an environment with insecure/self-signed certs. Finally it adds codecov to TPv2
