Injection Inception, Change #5: Add Access and Auth objects to DI

In CliMulti.php, check for test mode by checking for the PIWIK_TEST_MODE define instead of using class_exists.

Improve the contrast of the alerts so that they are more readable

Fix UITestFixture, add token auth to request to create dashboards since the controllers check for it.

Fixing test in CliMultiTest.php that fails now that loaded access is removed when the environment is recreated. So now in RequestCommand when the container is recreated, the Access instance is destroyed and the doAsSuperUser call is negated.

During Tracker authentication, make sure to reset the Auth instance's password/password hash (which can be set to previous values in tests during local tracking) and allow these values to be set to null in corresponding set methods of Login's Auth class.
