function FunctionalTestSetupTrait::rebuildContainer

Rebuilds \Drupal::getContainer().

Use this to update the test process's kernel with a new service container. For example, when the list of enabled modules is changed via the internal browser the test process's kernel has a service container with an out of date module list.

@todo Fix https://www.drupal.org/node/2941757 so that module enable/disable changes are immediately reflected in \Drupal::getContainer(). Until then, tests can invoke this workaround when requiring services from newly enabled modules to be immediately available in the same request.
