* remove misleading documentation about a "test failed" message, in
13.0 any uncaught exception or console.error will cause the current
test to be interpreted as failed
* fix tour manager to console.error its step and not add a second
useless error message
* fix menu tester to try and display the failure cause on failure
* improve qunit's test reporter to print the number of tests failed in
case of test suite failure
Should make test failures in tours a bit clearer.
