[BUGFIX beta] Fix positional parameters when used with component helper

[Serabe]

Updates positional parameters when component is invoked with the component
helper.

Uncomments the test, as asked in #13158.

Fixes #13158 in htmlbars

[Serabe]

More comments on this:

1. The code is not clean, not clean at all, but params and attrs are hard to deal with in htmlbars.
2. Positional parameters are coming to Glimmer 2 as well ([Glimmer2] Implement positional parameter #13393). They will need no fix when they are finished.
3. Shall I open a new PR for porting this to LTS?

I do not think we backport this into lts-2-4 branch. My reasoning is basically that this doesn't seem like a regression (as far as I can tell it has never worked)....

[Serabe]

It worked in 2.2. Twiddle

Thanks @Serabe!
