Fix TypeUtils.parameterize to work correctly with narrower-typed array

Currently the following code:
```
final TypeVariable[] variables = ArrayList.class.getTypeParameters();
final ParameterizedType parameterizedType = 
TypeUtils.parameterize(ArrayList.class, variables);
final Map mapping = Collections.singletonMap(variables[0], String.class);
final Type unrolled = TypeUtils.unrollVariables(mapping, 
parameterizedType); // exception !
assertEquals(TypeUtils.parameterize(ArrayList.class, String.class), 
unrolled);
```
throws an exception.

So, I added a test and fixed the ParameterizedTypeImpl class.
