RaiseArgs shouldn't autocorrect 3-arg form

[ptarjan]

---

Expected behavior

$ cat /tmp/a.rb
begin
  1 / 0
rescue => e
  raise StandardError, 'hi', e.backtrace
end
$ ruby /tmp/a.rb
/tmp/a.rb:2:in `/': hi (StandardError)
	from /tmp/a.rb:2:in `<main>'
$ cat .rubocop.yml
RaiseArgs:
  EnforcedStyle: compact

No autocorrect. Or if you want to get fancy you can autocorrect to

$ cat /tmp/a.rb
begin
  1 / 0
rescue => e
  new_e = StandardError.new('hi')
  new_e.set_backtrace(e.backtrace)
  raise new_e
end

Actual behavior

$ rubocop -a a.rb
Inspecting 1 file
C

Offenses:

a.rb:4:3: C: [Corrected] Provide an exception object as an argument to raise.
  raise StandardError, 'hi', e.backtrace
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

1 file inspected, 1 offense detected, 1 offense corrected
$ cat /tmp/a.rb
begin
  1 / 0
rescue => e
  raise StandardError.new('hi', e.backtrace)
end
$ ruby /tmp/a.rb
/tmp/a.rb:4:in `initialize': wrong number of arguments (given 2, expected 0..1) (ArgumentError)
	from /tmp/a.rb:4:in `new'
	from /tmp/a.rb:4:in `rescue in <main>'
	from /tmp/a.rb:1:in `<main>'
