colons catches not only usage at declarations

[kizu]

In Stylint 1.0.9 "colons": "always" gives warnings not only for usage with declarations, but also in some cases where there shouldn't be a colon.

1. Return statements:

   foo()
     return 'bar'
   
   .test
     width: foo()

2. Stuff inside mixins (conditions and some other expressions):

   foo()
     if $bar
       width: 10px

   foo()
     $bar = $baz

This is fixed in develop, it'll be in 1.0.10 when it goes up, once I take a look at some of the other issues / PRs

1.0.10 is out now, this issue should be fixed. Lemme know if you still have issues.
