Fix allow_tests instability.

  Meteor.apply('login', [], {wait: true});
  Meteor.call('setUpTests');  // creates some publishers
  Meteor.subscribe('oneOfThosePublishers');

The client will send the subscribe call before the setUpTests call due to
login's wait-ness, and then the subscribe will fail. We were basically doing
that in allow_tests.
