warning: loading in progress, circular require considered harmful

[ArtemDordovskyi]

Describe the bug

I see warnings about circular require every time I run rake tasks.

Steps to reproduce

1. Create rails application

rails new test-bugsnag
cd test-bugsnag

2. Update rubygems

gem update --system

2. Add bugsnag to gems

bundle add bugsnag

3. Add $VERBOSE = true to ./config/application.rb config file at the top

# ./config/application.rb
require_relative "boot"

$VERBOSE = true

require "rails/all"

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

4. Then run command and see warning

bundle exec rake -T
