Allow Sets and Lists to be initialized to null (instead of an empty collection)

[Illapikov]

You should use 'initializeEmptyCollections' set to false to get null to list.

Guys, this is a super feature but why the property is called initializeEmptyCollections? It sounds like "if a collection is empty - initialize it".
It feels like the name should be initializeCollectionsEmpty instead (which reads "initialize collections making them empty").

(I am not a native speaker so, obviously can be wrong)

Also it feels like a test is missing. I am not sure about jsonschema2pojo test policy but I personally would test it.

Thanks

Good point. How about simple initializeCollections? I think it's pretty obvious that 'initialize' implies that we will assign an instance (rather than null), and that for collections those instances will be empty if there are no default values supplied.

Regarding the test, good spot @dimas thank you. Somehow the integration test has been lost as the PR was prepared. There is a full set of integration tests in Illapikov/jsonschema2pojo@953c1012a4863275776352ce1bc0f1f74c80a5e1 and I didn't notice that this file was missing from the PR. @Illapikov don't worry about making any further changes, I'll grab the missing InitializeCollectionWithNullIT from that commit and add it to the project.

"initializeCollections" is even better.

Thanks!
