Autocorrection bug in Style/RedundantConditional cop

[pocke]

If "bad" code has elsif, Style/RedundantConditional generates wrong code when autocorrect.

if cond
  foo
elsif x == y
  true
else
  false
end

---

Expected behavior

Autocorrection generates the following code.

if cond
  foo
else
  x == y
end

Actual behavior

Autocorrection generates the following code actually.

if cond
  foo
  x == y
end

Steps to reproduce the problem

1. Put the above code as test.rb
2. Run rubocop -a

RuboCop version

master(ce6483c)

Good catch! I can see this happening with how parser nests the AST for elsifs.
