Triple the speed of E2E tests and stop them exploding if a circular datastructure is logged (#8095)
* stop e2e tests exploding if a circular datastructure is logged it's valid for the webapp to log datastructures to the console which happen to be circular but the e2e test running explodes badly with a runtime exception and bombs out before logging anything or providing a sensible stacktrace. you can trap the exception though and get a sensible error however. * don't barf on circular refs in return vals either and log timestamps * log timestamps * speed up roomDir & E2EE tests by 3x use timeouts correctly, so the first set of scenarios take 42s to run rather than 2m21s * speed up space test by 20spull/21833/head
