JS error caused by toolbar library when toolbar is not present

These changes (on that branch) fix the issue: https://git.drupalcode.org/issue/navigation_extra_tools-3515628/-/commit...

Thank you for submitting the fix. However, you don't appear to have opened a merge request. I'd be grateful if you could open one.

What is the reasoning behind removing the autowire form the legacy hooks? I was under the impression autowiring was needed for backwards compatibility of legacy hooks.

@seanpb Thanks for reporting this, and providing the fix. However, it still needs a merge request.

Is there a way we could add a test to check for the JS error to ensure I don't unwittingly break it again?

I forgot to set back to needs work in my previous comment.
