1. Fix a false positive for Lint/NumberConversion …

   This PR fixes the following false positive and incorrect auto-correct
   for `Lint/NumberConversion` when `:to_f` is one of multiple method arguments.
   
   ```console
   % cat example.rb
   delegate :to_f, to: :description, allow_nil: true
   
   % bundle exec rubocop --only Lint/NumberConversion -A example.rb
   (snip)

   example.rb:1:1: W: [Corrected] Lint/NumberConversion: Replace unsafe
   number conversion with number class parsing, instead of using :to_f, use
   stricter { |i| Float(i) }.
   delegate :to_f, to: :description, allow_nil: true
