Style/ConditionalAssignment autocorrect does not work with constants

[aevernon]

If I run rubocop -a on the following code:

if fruit == 'juicy'
  CHOICE = 'apple'.freeze
else
  CHOICE = 'grape'.freeze
end

It autocorrects it to this:

 = if fruit == 'juicy'
  'apple'.freeze
else
  'grape'.freeze
end

But it should be this:

CHOICE = if fruit == 'juicy'
  'apple'.freeze
else
  'grape'.freeze
end

$ rubocop -V
0.36.0 (using Parser 2.3.0.1, running on ruby 2.2.4 x86_64-linux)

I have a fix for this coming up
