Style/RedundantCondition can generate syntax errors when safe-auto-correcting

[renatolond]

In certain situations, Style/RedundantCondition can generate a syntax errors.

---

Expected behavior

I'd expect rubocop to either not auto correct (since it was supposed to be a safe auto-correction), or to not generate invalid code.

Actual behavior

rubocop generated code with invalid syntax.

Steps to reproduce the problem

I had a code like this:

def func
  a = 1

  if a
    return a
  else
    raise "Something went wrong"
  end
end

Style/RedundantReturn corrected it to:

def func
  a = 1

  if a
    a
  else
    raise "Something went wrong"
  end
end

Which then Style/RedundantCondition auto corrected to:

def func
  a = 1

  a || raise "Something went wrong"
end
