1. Fix an incorrect auto-correct for Style/SingleLineMethods …

   This PR fixes the following incorrect auto-correct for `Style/SingleLineMethods`
   when defining setter method.
   
   ```console
   % cat example.rb
   def foo=(other) @foo == foo end
   
   % bundle exec rubocop --only Style/SingleLineMethods -a
   (snip)
   
   Inspecting 1 file
   C
   
   Offenses:
   
   example.rb:1:1: C: [Corrected] Style/SingleLineMethods: Avoid
   single-line method definitions.
   def foo=(other) @foo == foo end
   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   
   1 file inspected, 1 offense detected, 1 offense corrected
   ```
   
   ### Before
   
   Auto-corrected to invalid syntax because setter method cannot be defined in
   an endless method definition.
   
   ```ruby
   % cat example.rb
   def foo=(other) = @foo == foo
   
   % ruby -c example.rb
   example.rb:1: setter method cannot be defined in an endless method definition
   def foo=(other) = @foo == foo
   ```
   
   ### After
   
   ```ruby
   % cat example.rb
   def foo=(other)
     @foo == foo
   end
   ```
