Description

The mention list variables are completely misused, fixing them so we can actually use the feature properly.

Tested locally with BROLOG_LEVEL=silly with extra console logs to verify that the variables are properly passed through.

Does this PR introduce a breaking change?

[ ] Yes
[x] No

[lhr0909]

I really don't feel like writing a test for it, testing alone takes out most of my energy. Please advice.

@lhr0909 Good catch! Thanks for fixing it.

I'll merge this PR after @windmemory approved it.

The unit test is better to have, but it's ok to leave it as is. Hopefully, we will have enough resources to cover them in the future.
