Improve test annotations

[gotbadger]

Description & Reproduction

For testing rules we use an annoation format

In this case the expected finding is expected to come from the line of the comment

begin
  1/0
rescue ZeroDivisionError => ex
  # bearer:expected ruby_third_parties_airbrake
  response = Airbrake.notify_sync(current_user.first_name)
end

In this case the expected finding is correctly marked as the line below the annoation

begin
  1/0
rescue ZeroDivisionError => ex
  1+1
  # bearer:expected ruby_third_parties_airbrake
  response = Airbrake.notify_sync(current_user.first_name)
end
