Spaces after ternary operator colons are reported/corrected twice

[owst]

Consider the following simple Ruby source file:

➜  /tmp cat foo.rb
'a' == 'b' ? 1 :2

Using Rubocop 0.39.0 (using Parser 2.3.0.7, running on ruby 2.2.3 x86_64-darwin14) the following offenses/corrections are listed:

➜  /tmp rubocop -a foo.rb
Inspecting 1 file
C

Offenses:

foo.rb:1:16: C: [Corrected] Space missing after colon.
'a' == 'b' ? 1 :2
               ^
foo.rb:1:16: C: [Corrected] Operator : should be surrounded by a single space.
'a' == 'b' ? 1 :  2
               ^
foo.rb:1:16: C: [Corrected] Surrounding space missing for operator :.
'a' == 'b' ? 1 :2
               ^
foo.rb:1:17: C: [Corrected] Unnecessary spacing detected.
'a' == 'b' ? 1 :  2
                ^

1 file inspected, 4 offenses detected, 4 offenses corrected

Notice that the since both Style/SpaceAfterColon and Style/Style/SpaceAroundOperators logged and corrected offenses, Rubocop generated double spacing after the colon, which it then detected and corrected. Indeed the file is corrected properly:

➜  /tmp cat foo.rb
'a' == 'b' ? 1 : 2

I think Style/SpaceAfterColon should not handle spaces in a ternary operator, which would avoid the double reporting and too much correction.
