Properly expectDeprecation when test parameter is a function

[bantic]

Ember.deprecate is called with (message, test, options). When
test is falsy or a function that evaluates to falsy, the deprecation
is issued.

expectDeprecation was correctly evaluating the test param when it is
a function, but not pushing the correct result of that function into
actuals. This made using expectDeprecate fail for a deprecation that used
a test function.

Example:

// Ember code
function foo() {
  Ember.deprecate('message', function() { return false; });
}

// test code -- this test would erroneously fail because
// expectDeprecation pushes ['message', function() { return false; }]
// onto actuals instead of ['message', false]
expectDeprecation(function() {
  foo();
}, 'message');
