fix(util/index): fix arg type & fn calls

It's not working when calling functions with named parameters,
there is no argument interface for the deleteMessage method in
Telegraf framework so I changed it, and there's a telegram
argument with the wrong type, and community might be null
on isDisputeSolver.
