Bug: Same dependency/dependee listed multiple times

[reneroth]

... if used more than once in a function/mixin

Stupid example:

@function double-value($value) {
  @return $value * 2;
}

@mixin doubledouble($attribute, $value) {
    #{$attribute}: double-value($value) + double-value($value);
}

Will state that doubledouble requires double-value 2x

I will try to look into this as soon as I find the time.

just fyi the linked closed PR is a functional fix for this :)
