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 20s
