having - requires explicit type parameter on higher kinded types

[nargov]

If a class is defined with type parameters such as

class HigherKind[T](kind: T)

Then this code does not compile:

"support having with higher kinded types" in new Context {
  val dummy = mock[Dummy]
  checking {
    oneOf(dummy).higherKinded(having(any[HigherKind[_]]))
  }
  dummy.higherKinded(new HigherKind("123"))
}

The error message is:

Error:(285, 41) type mismatch;
 found   : org.specs2.matcher.Matcher[com.wix.common.specs2.HigherKind[_]]
 required: com.wix.common.specs2.HigherKind[_]
        oneOf(dummy).higherKinded(having(any[HigherKind[_]]))
                                        ^

while adding the explicit type parameter on having gets it to compile.

"support having with higher kinded types" in new Context {
  val dummy = mock[Dummy]
  checking {
    oneOf(dummy).higherKinded(having[HigherKind[_]](any[HigherKind[_]]))
  }
  dummy.higherKinded(new HigherKind("123"))
}

Fixed in #13.
