Errors during bootstrap SILENCED

[vojtajina]

Errors during instantiation should be delegated to $exceptionHandler, errors during config phase should be probably just rethrown.

angular.module('app', [], function() {
  throw new Error('SILENCE');
}).controller('ErrorCtrl', function(err) {
  throw new Error('AGAIN SILENCE');
}).factory('err', function() {
  throw new Error('IGNORED AS WELL');
});

this is likely related to #1033

I'm got burned by this recently. We must fix this asap. Assigning to myself!
