path.alias_manager.cached error

tldr; $path_alias = /drupal_strtolower(drupal::service('path.alias_manager.cached')->getPathAlias($path)); broke my site
===
Installing the latest version of colorbox crashed my D8 site. I got a blank screen showing only:

If you have just changed code (for example deployed a new module or moved an existing one) read http://drupal.org/documentation/rebuild

I followed the steps, it didn't help in this instance. I then got lost in reading serialized PHP in the DB to try to disable it. No avail :/

The PHP logs said:

Exception thrown when handling an exception (Symfony\\Component\\DependencyInjection\\Exception\\ServiceNotFoundException: You have requested a non-existent service "path.alias_manager.cached". Did you mean this: "path.alias_manager"?)

I found the line in the .module that references "path.alias_manager.cached" and changed it to "path.alias_manager" but then I got a new error calling an undefined function. I ended up just changing line 92 to (in order to match path):

$path_alias = current_path();//drupal_strtolower(drupal::service('path.alias_manager.cached')->getPathAlias($path));

AND IT WORKED!
