SwaggerSpecFilter with removingUnreferencedDefinitions, removes definitions within containers (List/Map)

[mtraynham]

The example condition is at (but there are other lines just like it):
https://github.com/swagger-api/swagger-core/blob/master/modules/swagger-core/src/main/java/io/swagger/core/filter/SpecFilter.java#L140

if (response.getSchema() != null && response.getSchema() instanceof RefProperty) {

As an example:

public List<Foobar> getAll() {
    ...
}

Will filter out the FooBar definition, as the operation's response is an ArrayProperty which does not extend RefProperty.

public Foobar getAll() {
    ...
}

Retains this property correctly...
